There is no reason one should not realize the gains, I have held coins worth thousands of dollars until they went bust, I know it's probably cause they were shitcoins and story would have been different if it had been BTC/ETH but It's always good idea to take profit. When to sell? No one can tell you, best thing I have come across is DCA all the way out as Poker Player mentioned.



I'd choose stable coins, it's easy to go back to crypto with it than fiat, also most countries impose tax on fiat-crypto conversions and not on crypto-crypto.
