    What is a medium of exchange and how
    does a modern money become a medium of
    exchange? So any modern money, if you
    look this up on chat GPT or on Google or
    you know Wikipedia, whatever, it’s going
    to tell you money has three primary
    attributes. It is a store of value. It
    is a medium of exchange. It is a unit of
    account. When something is becoming
    monetized, it goes through those three
    stages. initially as only a store of
    value, then as a medium of exchange,
    then as a unit of account. And
    oftentimes you hear people criticize
    Bitcoin because they say, “Hey, people
    are not buying coffee with it every
    day.” Well, I am. I don’t drink coffee,
    but I buy stuff with Bitcoin all the
    time. But people don’t understand that
    those three stages do not happen
    simultaneously. When something is
    becoming a new money, it does not have
    all three attributes simultaneously. It
    goes through three stages. The first of
    those stages is always store of value.
    And the reason that stage is always
    first is because people will not
    exchange something that they do not
    perceive to have value. So you would
    never start a money and have it become a
    medium of exchange immediately. And the
    reason is because nobody will exchange
    something that does not have value. So
    they will only exchange things when
    people on both sides of the transaction
    perceive it to have value. And Bitcoin
    does have value because of its monetary
    properties. So eventually enough people
    were using Bitcoin as a store of value
    because of its monetary properties that
    one person gave someone else Bitcoin for
    something in the real world, a you know,
    pizza or whatever it was. You know, the
    very first transaction was for two Papa
    John’s pizzas. But that is because one
    person had Bitcoin, the other person
    wanted Bitcoin, and that transaction
    happened. uh but they both had to
    perceive Bitcoin to be a store of value
    first because otherwise they never would
    have made that transaction. Okay. So
    when a money is becoming a money, it
    goes through store of value, then medium
    of exchange, then unit of account. But
    since this video is about medium of
    exchange, let’s walk through what it
    means to be a medium of exchange. Let’s
    go through some simple examples. One,
    when you buy something in the real world
    with cash, your medium of exchange is US
    dollar cash. And the recipient’s medium
    of exchange is also US dollar cash. You
    are handing them US dollar cash. They
    are receiving US dollar cash. The medium
    of exchange is US dollar cash for both
    parties. But most transactions are not
    done with cash. So let’s say the
    transaction happens with a debit card.
    So if if a debit card is used, your
    medium of exchange is US dollars and the
    recipient is also receiving US dollars,
    although typically with a time delay.
    Okay? But it gets more interesting if
    you introduce credit cards because
    people perceive credit cards to be
    entirely a US dollar medium of exchange.
    But if you think about it, and again I’m
    not saying this is technologically
    correct scientifically or you know
    according to economics books. I’m just
    saying let’s think through it together.
    The way it logically makes sense is what
    you are actually spending with a credit
    card is not US dollars. You’re spending
    US dollar credits because US dollars did
    not actually leave your possession. what
    what actually left your possession is
    you became indebted to Visa or
    Mastercard but the actual dollars did
    not leave your account because that
    happens later once a month or you know
    if you don’t pay your credit card bills
    it’s you know significantly delayed so
    you are paying with US dollar credits
    but the recipient even if it’s time
    delayed is receiving US dollars from
    Mastercard or Visa or American Express
    so in that case you’ll notice that the
    medium of exchange for both parties is
    not the Same thing. Your medium of
    exchange when you use a credit card is
    US dollar credits, but the recipient is
    receiving actual US dollars from Visa,
    Mastercard, Discover, or American
    Express, even though those companies are
    not actually receiving the the US
    dollars from you until the end of the
    month or potentially if you don’t pay
    your bills, a much delayed place. Now,
    Bitcoin is often criticized by people
    who say, “Wait, you know, if I’m using a
    Coinbase debit card in the real world,
    it’s not really Bitcoin because the
    recipient is receiving US dollars.” That
    is true, but that is also true every
    time you use a debit card of any kind in
    a foreign country. So, I travel down to
    Honduras a lot to uh visit the our
    development there on the island of
    Roaton. Okay. Okay, when I’m in Honduras
    and I’m using a Coinbased debit card,
    let’s walk through a transaction. What
    is my medium of exchange? My medium of
    exchange is Bitcoin because when I swipe
    or I use touchless payments on my Apple
    Watch, that’s basically how I pay for
    everything is with touchless payments on
    my Apple Watch with the Coinbase debit
    card. When I touch my watch to a payment
    terminal in Honduras, I am having
    Bitcoin reduced from the balance in my
    Coinbase account, which I keep at pretty
    low levels, but it’s always enough that
    a debit card transaction will process.
    Okay. So, I’m having Bitcoin reduced.
    So, that is my medium of exchange is
    Bitcoin. The recipient is getting
    Honduran Limpira. So, their medium of
    exchange is Honduran Limpira. My medium
    of exchange is Bitcoin. Now again, some
    people would criticize that and say
    Bitcoin is not being used as a medium of
    exchange. But the truth is, anytime
    you’re traveling internationally, US
    dollars are not your medium of exchange.
    First of all, we already talked about
    the fact that if you’re using a credit
    card, your actual medium of exchange is
    really US dollar credits, not actual US
    dollars. But if you are traveling
    internationally, whether you are using a
    credit card or a debit card, the
    recipient is typically not getting US
    dollars. So, if you’re using a debit or
    a credit card in Europe, the recipient
    is receiving euros. If you’re in Japan,
    they’re getting yen. If they’re in
    China, they’re getting one. If you’re in
    Switzerland, they’re getting the Swiss
    Frank. If you’re in Honduras, they’re
    getting the Limpira. And if you’re in
    Venezuela, they’re getting the
    Venezuelan Bolivar, if anybody even
    accepts the Venezuelan Bolivar anymore
    after 50 million% inflation. Literally
    50 million% inflation. Um so in in that
    case uh people think that the medium of
    exchange is US dollars although they
    don’t really realize it but the truth is
    no Visa, Mastercard, American Express or
    Discover are making a translation for
    you. Part of the service that they are
    providing in exchange for getting about
    3% or around 2.9% credit card
    transaction fees is making a conversion
    for you. They are allowing you in the
    case of a US dollar debit card, they are
    allowing you to use US dollars as your
    medium of exchange, but the person in
    Europe is receiving euros as their
    medium of exchange. Now, you could
    criticize the US dollar in that
    scenario, just like sometimes people
    criticize my use of a Coinbased debit
    card, saying that’s not real Bitcoin
    because the recipient is not receiving
    Bitcoin. Well, my question is, okay, if
    you’re using a a US dollar debit card in
    Europe, does that mean those are not
    real US dollars? Well, of course they’re
    real US dollars. Your bank account is
    getting reduced by US dollars when you
    use a debit card in Europe. The it just
    so happens that Visa, Mastercard,
    American Express, or Discover is doing
    the courtesy for you behind the scenes
    of transacting in foreign currency. They
    are converting the US dollars that they
    took from your bank account to euros and
    they are handing those euros minus a
    small processing fee to the recipient on
    the other end. So in that case again
    very often in the modern economy the
    medium of exchange for each side of the
    transaction is different. Um if you are
    using a US dollar debit card your medium
    of exchange is always US dollars. the
    recipient is getting all sorts of things
    and the the recipient’s medium of
    exchange is whatever the local currency
    is that they have negotiated to receive
    by Visa, Mastercard, American Express or
    Discover. Okay? So, if I’m using a
    Coinbase debit card, then my medium of
    exchange is Bitcoin because Bitcoin is
    what I am losing as a result of
    initiating a transaction. The recipient
    if I use au a uh bitcoin debit card in
    the United States is receiving US
    dollars. But again their medium of
    exchange is dollars. My medium of
    exchange is bitcoin. But very frequently
    in the modern economy the medium of
    exchange is different for each side of
    the transaction because we live in a
    complex modern economy where Visa and
    Mastercard are willing to make those
    translations for us. All right, let’s
    walk through one especially complicated
    example, which would be the Coinbase
    credit card. Not the Coinbase debit
    card, but the credit card. Okay, when
    you use a Coinbase credit card, you are
    transacting, your medium of exchange is
    US dollar credits, just like any other
    credit card. So, the entire month
    between billing cycles, your medium of
    exchange with the Coinbase credit card
    is US dollar credits to American
    Express. in this case because Coinbase
    uses American Express for their credit
    card and they use Visa for their debit
    card. But since we’re talking about the
    credit card, that would be American
    Express. So, you are using US dollar
    credits on the American Express network
    when you transact with the Coinbase
    credit card. Now, when it is time to pay
    off your bill, you can choose to pay it
    off with your Bitcoin balance, which
    because I keep effectively zero US
    dollar balances, that means if I’m ever
    using the Coinbase credit card, which I
    alternate between the credit card and
    the debit card depending on what I’m
    buying or what I’m using it for. Uh the
    credit card has a higher limit on it
    more than $2,500 per day. So, sometimes
    I use the credit card if I’m traveling
    for airline or uh hotel accommodations.
    If they exceed $2,500 for an entire trip
    for my family, for example, I’ll use the
    credit card from Coinbase. But once a
    month, when it’s time to pay that bill,
    I pay it from my Bitcoin balance. So, at
    that point, my medium of exchange to
    American Express via Coinbase is
    Bitcoin. So in the case of a credit
    card, there’s actually two medium of
    exchanges for the person using it. The
    medium of exchange at the time of
    purchase is US dollar credits. The
    medium of exchange at the time that the
    uh the credit card statement is p paid
    off in my case with the coinbased credit
    card is Bitcoin. So again, we live in a
    complex world. medium of exchanges are
    easy to sort of interchange because
    Visa, Mastercard, American Express, and
    Discover and numerous others are willing
    to do all sorts of fancy currency
    conversions to allow you to spend
    virtually any currency in virtually any
    uh location and have the recipient get
    the currency of their choice, which is
    why it’s so easy for me to live
    exclusively on Bitcoin. I can use the
    Coinbased debit card, and with the
    Coinbased debit card, my medium of
    exchange is Bitcoin. The recipient’s
    medium of exchange is whatever they’ve
    negotiated uh with the credit card
    processing organization. Now in the case
    of Cash App uh you can actually choose
    if the vendor allows you to pay with
    Bitcoin and chooses to accept in Bitcoin
    then the medium of exchange is Bitcoin
    and Bitcoin on both sides. If the vendor
    using uh the square payment terminals
    which is made by the cash app people if
    they have set it to receive US dollars
    then uh the company square or
    technically block is their company name
    but the the product name is square and
    it’s made by the cash app uh the company
    behind cash app and bit key they’re all
    made by the same company which is uh uh
    run by Jack Dorsey the former founder or
    the founder of Twitter before he sold it
    to Elon Musk. Um, in that situation, you
    can choose in the Square payment
    terminals whether you want the medium of
    exchange as the recipient uh of that
    transaction to be Bitcoin, US dollars or
    whatever. And then at the payment
    terminal itself, you can choose whether
    you want to pay in US dollars or pay in
    Bitcoin and it will let you do either.
    So hopefully this primer on medium of
    exchange is helpful. As always, any
    money goes through the process of
    becoming a store of value first, then a
    medium of exchange, then a unit of
    account. That process often takes uh
    definitely years, but often decades
    between each of those stages. Bitcoin is
    firmly uh in the store of value stage.
    It is in the very early stages of medium
    of exchange and almost non-existent as a
    unit of account. Very very very rarely
    do you see things that are priced in
    Bitcoin. As soon as you start seeing
    lots of things that are priced in
    Bitcoin, you will know that Bitcoin has
    started down the road of becoming a unit
    of account in addition to its current
    function as a store of value and the
    emerging early stages of being a medium
    of exchange. But again, with a credit
    card or debit card network, you can have
    lots of different medium of exchanges on
    each side of the transaction. And with
    things like Square and Cash App, you can
    choose whether you want your medium of
    exchange to be US dollars or Bitcoin on
    both ends. So you can pay with US
    dollars and the recipient can receive
    Bitcoin. You can pay with Bitcoin, the
    recipient can can receive uh uh US
    dollars or you can pay in Bitcoin,
    receive Bitcoin, or you can pay in US
    dollars, receive US dollars. The Square
    payment terminal lets you configure it
    where depending on what they pay with,
    you can choose how you get paid. And
    again, that gives you four different
    options. US dollars to US dollars, US
    dollars to Bitcoin, Bitcoin to US
    dollars, or Bitcoin to Bitcoin. And it
    supports them all. And that is likely to
    be the case for a lot of payment
    processors uh for the near future where
    as more and more come online, you have
    the choice of Bitcoin or US dollars on
    paying and receiving, and it will do
    anything you want in between there to
    give you exactly what you want. Uh
    hopefully that’s helpful. I hope to do a
    lot more videos on each of the different
    functions of money, and I’m here to help
    if you need anything. The bags.

What is a “MEDIUM of EXCHANGE”? What is the process for a new
money to become one?
