cryptos are the most centralized decentralized product to ever centralize. honestly, the marketing on cryptos is amazing.   other than just using a bank account and using cards. if the rich wanted to flee entirely with all their wealth, they buy and sell brokerage assets such as stocks, bonds, hisa, other currencies, etc. fiat can be transferred basically anywhere anytime.  meanwhile, if you buy crypto, by the time you travel over the border, you could lose 50%+ of your wealth simply due to the fluctuations crypto suffers. and where you move, there's a very high chance the country has little or no infrastructure to use the crypto or convert it back to useful fiat currency and buy assets again.
