I had my money - which at the time include the proceedings of working a few years in Finance - spread over 3 bank accounts in 3 countries back then and came through it all with no loss whatsoever.
Further, crypto is so stupidly volatile that even stocks are better at protecting your wealth because you’re actually less likely to see half its value gone in a week with stocks (incredibly unlikely, even, if you get a tracker fund on a major index).
And don’t get me started on the ultimate most conservative (literally capable of surviving the collapse of modern civilization) wealth protection thing around - gold.
The point being that unless you expect the collapse of modern civilization (in which case you might try gold or, even better, tradeable essential needs like the kind of food that doesn’t spoil easily such as dried pulses), the best way to safekeep your wealth is as usual Diversification, with a focus on things with a stable value, which crypto is definitely not.
Yeah, but today is always the first day of the rest of your life.
