You could afford to lose 10+ million without your life being detrimentally impacted (at least I would assume, based on how calm you are about it). Most people can't. Most people can't imagine that amount of money.
I'm not a crypto fan. While the technology is interesting and has some intriguing use cases, it feels like all the big coins far away from actually becoming a legitimate currency, and most of the optimistic posts I read miss that.
Crypto is not stable. I think that's why so much money is flying into it. If the price of bread or milk goes up 10%, people get scared. In crypto, going up or down 10% is called "Wednesday". I'm aware of stablecoins, but the biggest ones (Tether, etc) all seem to A: be centralized, and B: be run by shady groups with whispers they could disappear at any moment. A breaks the promise that crypto is supposed to provide, and B only provides stability at a glance, until the whole house of cards tumbles apart (as it has).
The bigger problem is that crypto is unforgiving. OP's story is all about this. Sure, that's fine for techies who can afford mistakes, and banks or other who might have extreme security procedures, but Mom and Pop on a farm in Iowa are neither of those. When they get a phone call from the "IRS", they are happy to go buy Walmart gift cards and read off the codes, or set up a money transfer. Sometimes that money can be reclaimed, sometimes it can't. With crypto, there is no chance. The financial institutions that exist now are certainly rigged towards the bigger players, but Mom and Pop have a (slim) shot of seeing the money again.
Crypto is a fine gamble for those who can afford it, but I honestly doubt it will ever be an every day currency, because I can't see any concerted effort focused on solving those two problems. People can't afford to not know what everything costs at the grocery store, or that they could lose their entire savings by making a mistake when buying a Christmas gift. I don't think it's a great store of value either long term, because at least traditional stores of value (land, precious metals, commodities, etc) have uses to the entire population - blockchains provide no value to 73 year old grandma.
