Price don't go down because they could be scam, but all market go down...
Correct. Bitcoin is going down; therefore, all alts are going down with it. As long as Bitcoin remains bearish, alts will remain bearish. Smart traders don't hodl at all costs; they buy and sell when it makes sense to. There is no guarantee prices will return to what they were. But there is profit for those who are wise enough to take it.
