Yes, if for the time being it's better not to sell first because the price of Bitcoin and Ethereum is in good condition and always has a good increase, and I think people who don't have the chance to buy BTC and ETH when the price is still cheap will feel a little sorry to currently.
Indeed for BTC and ETH it is very good to hold now, but not for other coins. I see a lot of coins falling today because Bitcoin dominance continues to increase. This is where the Crypto market situation in the Bullish period, but only for top coins, like BTC, ETH etc.
