Possibly. I am not a believer in fiat going away. I do however believe Bitcoin will continue to siphon global money and assets forever and take over gold and real estate(as an investment/asset).

I don't believe in fiat going away either. That's why I mentioned it is probably worthwhile still having some fiat currencies stashed away. Aged bank accounts are always helpful as well when needed. I'm more for separation of currencies, whether crypto or fiat. I think bitcoin is America's hedge against its defaulting debt. China and Russia chose gold as the same. Maybe in their case a secondary goal is using hard money as a way to move farther away from dependencies on US treasuries. Whether bitcoin will be a useful investment or store of value will depend on where one is in the world or what they intend to accomplish. For example, IMHO I think fuck boi NGU American maxis will eventually want to come back into fiat when they want to cash out. So for that kind of individual, residing in America. Buy bitcoin, ride the wave if investment is your goal. However in China, the wealthy want to use bitcoin as an additional tool (they also do a lot of retail arbritage overseas) to help them deal with currency restrictions put on them when trying to move money to foreign currencies. Most of them opt for gold as a store of value though because it is easier to liquidate than BTC for example
