Well, we will just have to agree to disagree.

No, no, hear them out. It’s actually super great that when you walk into the grocery store the loaf of bread is $1.50, and by the time you walk to the bread aisle it’s $0.72, and by the time you walk to the cashier it’s $2.10. This is actually super great, because there’s also a medium country’s worth of electricity being consumed to enable that.

It fluctuates with an I narrow range, and as it gets more adoption, that range is continuing to narrow. As a matter of fact, I sell items for Monero and I keep my prices completely stable and people do come to buy things. https://xmrbazaar.com/user/shortwavesurfer2009/. I have my prices set in such a way that they will stay stable until at least December 1st of 2024 at which time I will update them if need be.

You should not be investing money in something based on this level of understanding

IMO, you shouldn’t be investing in cryptocurrencies or any currencies for that matter. Currencies should be used, not hoarded with the expectation of gain. If you’re buying cryptocurrencies as an investment, you’ve already lost.

Where cryptocurrencies have value is as a medium of exchange. In many parts of the world, the central bank isn’t trustworthy and end up causing runaway inflation, such as in Venezuela, Argentina, and Turkey. This is because there is a lot of political gains to be had by manipulating the currency to make things appear better than they are. The US hasn’t had this issue largely because the Federal Reserve is largely immune to politics (they’re appointed by the executive and confirmed by the Senate, but that’s about it). But that’s not guaranteed to always be the case. Board members can be removed, and the President and Senate can theoretically pack the Federal Reserve board in the same way as packing the Supreme Court.

The great thing about cryptocurrencies is that you don’t need to trust anyone to use it. Here are the parties involved in a transaction:

• you
• the other party
• miners verifying blocks
• source code maintainers

Each of those has checks in place. You and the other party don’t need to exchange secrets, only information that is totally acceptable to be shared (pub keys, not private keys). With something like Monero, you can even make a separate key for each transaction if you’d like. Miners compete against each other to validate transactions accurately, and if a miner tries to cheat, their results are excluded. Source code maintainers work in the open, so researchers (or you!) can and do look at the code.

With fiat, you have to trust the central bank and banking regulators. If you don’t trust your central bank, you’re SOL.

The cost of using a cryptocurrency vs a central bank is that lack of central oversight, meaning you’ll see more variation in valuations. However, this should smooth out as more people use it as a currency (so more even inflows vs outflows). There isn’t something like the US dollar or Euro’s target 2% inflation rate, so we could see deflation instead of inflation if cryptocurrencies catch on or if people flee to it from investments in a bear market or something.

The value of a cryptocurrency is the demand for that currency. Just like fiat, it has value if we believe it has value. Fiat currencies aren’t based on anything more than supply and demand for that currency, just like crytocurrencies, with the big distinction that valuations also take into account trust in the backing back (whereas cryptocurrencies include trust in the network and code).

While I personally agree that we should not store all transactions for all time, our storage capability is going to get exponentially better. We are able to store data in 3D discs with lasers now and can store petabytes in a single disc the size of your typical old CD-ROM and even store data in DNA if we wish. These obviously aren’t going to be included in your desktop computer anytime in the near future, but they do currently exist and show that storage will not be a problem for a very very long time.
