We all know that around summer time this year most altcoins went up extremely fast and big in price, right?
So isn't it normal that a big sell off taking place at some point? Especially in such a new market people getting scared and dump their holdings when the market goes
down a little bit and then it goes down more and more - chain reaction. It's very bad for people who bought alts at the top. So you have two options, hodling or selling with a loss. I would always prefer the first option.
Be patient and hodl. A lot of alts will come back someday and some probably never come back so I hope you diversified your portfolio.
