I think you are too pessimistic if you think like that. The incidents we face today with the crypto currency price are that came down drastically has occurred also a few years back if I'm not mistaken. Perhaps this is the beginning of the revival of the crypto currency in my view. So i wish the cyrpto currency will be rise up immediately. Sometimes I feel worried about crypto currencies at the current circumstances, but I also believe in the future of this crypto currency that will be bright. 
I think it is understandable that some people are worried about what it may happen in the future after the crash, but people that have been around for a long time have already lived through different crashes and know this is not different, for many people this was the first crash and they are scared about what happened but cryptocurrencies are going to recover sooner or later so the best thing you can do is to hold and to try to not worry too much.
