If I were you I wouldn't sell all of the cryptos I own, rather sell some of them to get my profits and hold the remaining because I feel the bull run is going to continue for quite some time now.
I think the same as you. There is no need to sell all our coins, just sell some coins that are already increasing at good prices to sell. For some coins that the prices are still decreasing, it is better to keep holding them. The sign for the upcoming uptrend is still there, I am also confident that the bullrun isn't over yet. What we must do is to be patient waiting for the beginning of the next pump of all crypto coins, especially for Bitcoin. When Bitcoin is increasing significantly again, all altcoins probably will increase their values as well.
@bhooscream exactly and with the current market dip i think it's a great opportunity for people to buy some more fundamentally strong cryptos and reap profits when the market rises.
