This is because of the dumpings of bounty hunters and airdrop hunters. Also, the banning of cryptocurrency in various countries like USA and China affects this crisis. But don't worry, this will end. Nothing is forever, one day the market will become green again. All coin and those prospective tokens will also pump.

I suggest to hodl and buy those coins with a great prospect. It can give you huge profits years from now. Don't lose hope.
