If I bought and held my bitcoins from 2011 I would had 40 million $ today. The thing is either you're in or you're out. Either you believe in cryptos and that this is a gamechanger. You either DONT want your paper money any more, or you do.. Thats up to you. But trading usually goes wrong. You have to ask yourself "Do I believe this is the future of money" If the answer is Yes, you just hold it. Look at it in the same way you hold your gold and silver (and maybe even guns and bullets). Its an insurance against the current system. If it fails, youre hedged.
