Don't take this the wrong way, but you sound illiterate since you clearly don't understand the words I wrote in context "medium" and "exchange". The statement "You can't eat the medium of exchange" implies that it is to be spent.
There already many ways to exchange cash for assets that are likely to appreciate in value (gold, real estate, equities, bitcoin). Won’t a depreciating asset like cash always make for better incentives to participate in trade than an appreciating one?
Please explain the advantages you see in the simplest terms you can.
The features that make cash good as a medium of exchange are not appreciation or depreciation, but all of the other features of divisibility, fungibility, transferability, common acceptance etc. A good medium of exchange need to be valued such that it can be reliably exchanged. Ideally you don't want it going up too fast nor down two fast, but stable enough to make trade. It just happens that Bitcoin is/ was very small relative to the global economy. It also has the benefit that it can't be debased, which makes it a better money - even for trade as well as saving. I just wouldn't consider it "investing" despite the fact it still has room to grow as a currency. It still needs much more work on the fungibility side.
If the primary medium of exchange is an inflating currency then possessors are incentivized to exchange it. If debt is owed in a deflating currency than the burden of all debts will only grow. Could you address these points rather than simply dismiss them as irrelevant?
Please note that I haven't dismissed any point you have made despite your initial dismissal of me.
To your point, is a currency is inflating then you are incentivised to not hold it. But who has the right to benefit from the inflation of the supply? How do you fairly determine that? Often inflation is conflated with the rise in prices rather than strictly the inflation of supply, so strictly referring to the latter - inflation occurs, while at the same time economic growth is also occurring, so it isn't 100% clear that the incentive scheme for devaluing a currency will work as it must balance against this growth. Even if it is not balanced, and successfully devalues for your incentive, what is the appropriate rate? Is VEF too much, USD just enough? Wouldn't it make more sense to just have a fixed/known rate of currency supply - eg Bitcoin - decreases to 0, Monero decreases to small.
The problem isn't so much the inflation, it is the unpredictable nature of the debasement and the fairness of who benefits from it. A currency doesn't need to incentivise people to spend it so long as it can always be available as a medium. Infinite divisibility ensures this. Having the medium be a universal standard measure as a unit of account by virtue of being a stable and accessible medium is also essential. Bitcoin achieves this. As for debt burdens growing, this is not always true. If I take a low interest BTC loan for mining equipment and have measured my risk and profit correctly I should be able to pay it off since I am working in this currency. If I borrow USD to start a Venezuelan corner store, I might be in for a bad time.
Inflation benefits borrowers more than hoarders. Your example is strange because in the one you compare a base currency to economic activity in that currency and in the other you take a loan in one currency in order to transact in another. If you borrow bolivars to start a Venezuelan corner store, at least your debt would lose value as rapidly as the currency you receive from your customers. If the price of BTC continues to rise indefinitely, you would be in for an even worse time if you borrowed BTC to start your Venezuelan corner store.
I also don't see how infinite divisibility helps. It's still deflation. Let's say the world converts to BTC. Now if I take a loan of 1 BTC to start my corner store, the value of that 1 BTC will continue to increase, but if the goods selling do not increase in price, I will have to charge less and less for them over time. There's the same amount of space between 1 and 0 as there is between 1 and infinity.
You can rephrase that as inflation benefits borrowers more that savers. And borrowers benefit lenders. In the opposite paradigm, savers benefit savers and savers benefit investors. Think of a scenarios that is made up of an economy of a single currency, that is deflationary and everybody saves as much as they can, but they have to eat, so trade still occurs. Those that can save more accumulate more purchasing power until they think it wise to invest and get a greater return. Assuming all perfect investment execution, wealth would tend to aggregate as we see, but overall everybody benefits and see the rising tide lift all boats.
Savers can choose to loan their currency to a bank for some guaranteed returns, they can loan it to corporations and public institutions in the form of bonds, or they can purchase ownership of real estate and businesses through equities. They can buy bitcoin if they consider it a wise investment. Only lenders and the people who insist on hoarding cash suffer from inflation.
Historically deflation has resulted in economic stagnation and depression. The reason is that there is no incentive to borrow or spend money on a risky investment when increasing value of currency over time is guaranteed. What exactly is supposed to be different this time?
