What if 2019 is the beginning of another dump?? What would you do as a investor?? Wait till your portfolio goes to zero?? ... or sell whatever is left of it??
If I was in that situation and I've lose too in my portfolio, I will choose to hold until it goes to zero. It's because I have faith in my holding and I believe that I will not invest in cryptocurrency at first if I knew that it's not beneficial to commnity. I will just tend to believe that losers are those who doesn't stand for their decision.
