Have you still hodl your ChainLink coin? If so, then you should hodl it for little more time cause you can see that price of ChainLink increasing and may possible act rarely bullish within short term. but if you don't know how to make maximum profit from your coin or don't like to take any risk anymore, then it is best to sold your coin cause now the price is good. Afterward i assume, you will find another chance for investment on another project
The price of ChainLink may be going up in terms of dollars but it is going down in terms of bitcoin as a great deal of money that was parked on altcoins is now coming to bitcoin again, so this is a difficult decision, if a bull market really comes it is likely that altcoins will grow as well but you never know how the market is going to react, after all we have had season in which the price of bitcoin went up and altcoins crashed and if that happens you do not want to be holding a coin like ChainLink which could crash really fast as investors leave it behind to get some bitcoin.
