I don't know which one is better investment because bitcoin, ada and link are the best coins to invest in my opinion. If you are still confuse choosing one of these three coins then maybe you should split your money into three, you can still make profit of these three coins once the market recover.
Op did not ask for choice a token. He just wanted to know if he bought LINK token and he is in a lot of losses. Should he sell that link now or hold more? I think he needs to hold those tokens now until the market is recovering and his tokens are making a profit.
