So I have yet to see what utility crypto provides besides "transactions are irrevocable and semi anonymous". (as a miner you are just a tulip farmer and are gaining only temporarily). Do you know of any? Smart contracts provide a way to do some limited forms of escrow.
So if you want to buy something online, presently:
You can use a credit card. A temporary virtual one. If the transaction isn't satisfactory you almost always get your money back simply by complaining. Fees are approximately 3% though hidden from you. A record of the transaction is held by your bank and can be obtained by investigators with a court order.
You can use crypto. Transactions are irrevocable and it is possible to get your money stolen from various forms of phishing or hack. Crypto may decline in value in real time while you are making the purchase. Fees can be tens of dollars including both exchange fees and transaction fees. The recipient may be using a temporary receiving address, so even if you use an exchange that keeps a record, investigators with a court order may not know what the money was used to purchase.
Basically, I don't know what legitimate use crypto has for those who aren't trying to break the law in some way. Whether the law is restricting contraband items (drugs and weapons and stolen information) or taxes or international funds transfers.
As a consequence, at some future point, Western governments may outright ban crypto exchanges. This has already happened before - look what happened to e-gold. They can't ban crypto directly, but banning the exchange of currencies controlled by western government for crypto and vice versa would crash it's value and reduce the number of users to a tiny number of people willing to go through the risks and hassles of evading the ban.
The main problem with deflation is mainly not about holding M1 but promises of payments that are denoted in the currency. When currency inflates it's relatively easy to raise the salary of employees to match the value of the currency. On the other hand when deflation happens, making salary cuts is much harder.
It's possible to write laws that force salaries to be payed in the currency that's preferred by the government for most legal employment.
You can write laws that make loans in crypto currencies not legally enforceable which prevents a lot of current loans that are backed by the governments power to seize future earnings of a person.
That said, even if you want to use crypto for denoting future payments of money using a stable coin like reserve makes much more sense then using bitcoin.
There were a few good points distributed over many answers and comments, so I’ll collate them here. I’ll ignore answers to other questions, such as “Is it likely that cryptocurrencies will get big?” I’ve paraphrased all of these.

Did I forget any?
Some cryptocurrencies, notably Bitcoin, are designed to be deflationary.
Bitcoin is not deflationary. It is slightly inflationary, much less inflationary than fiat currencies, but it is not deflationary.
Summary: Deflation (or so I heard) is considered harmful because it stifles growth. Central banks have been fighting it to keep economies healthy. Cryptocurrencies can be designed to be deflationary. If the market capitalization of cryptocurrencies becomes big, central banks may have no way to contain the deflation. This may be catastrophic in many ways – but might it also slow AGI development and buy safety research more time?
I’ve been wondering what the “crypto endgame” may look like. Crypto may just turn out to have been a bubble or may continue for decades unchanged at its current limited level of significance. But we’re probably sufficiently prepared for those scenarios already.
Instead the crypto market capitalization might take off at a superlinear pace. Bitcoin is currently on rank 14 among the world’s currencies and holds 0.7% of the aggregate value of all of them. All cryptocurrencies together hold about 1.1% of the world’s monetary value.
The crypto space is rife with network effects. Or it is one huge network effect. These are wont to show superlinear growth if they show any growth. Superlinear growth often doesn’t last long enough to be significant, but in other cases it does. So maybe crypto’s market capitalization will grow by an order of magnitude or more within a few years, so before AGI is developed. That might happen if more more companies follow the examples of MicroStrategy or Tesla and invest their spare cash into a cryptocurrency. Phil Bonello, director of research at Grayscale, also mentions a scenario in which governments start buying crypto and thereby force all other governments to follow suit. I don’t know the reasoning behind that, so I don’t know how forcible that effect will be, but it doesn’t seem to be hard to come up with plausible growth scenarios. (At least if you’re incentivized to come up with them the way Grayscale is.)
Some cryptocurrencies, notably Bitcoin, are designed to be deflationary. If companies across the board find that they generate greater profits by investing all their spare cash into deflationary cryptocurrencies rather than reinvesting into their own production, innovation may stall. (Isn’t that one of the typical reasons why deflation is considered harmful?)
So that brings me to my questions:
