Whatever happen do keep some of your coins that has good potential in the market, because in the next five years Billion of people are going to use cryptocurrency, so even if you have few satoshis in your wallet, it could still worth hundreds of dollars.
Maybe this can happen, but I think it takes a long time and if you believe it will give you a big profit, then hold some coins that you have for a long time. I think bitcoin and only a few other coins will be able to have a very high price later.
