save yourself and your money. don't be stupid, get out while you can before the bottom is reached.
don't bet all your money on a "hope" that this market will rebound, it may not.
take your profits and move on.
what profits man, most Poloniex Altcoins (except 4 or 5) are like -50% to -70% in the past 10 days
either the bottom is here or these coins are dead
