There are many exchanges that is on the market, many people also are focused on gaining profits on their cryptos.
I just noticed that Fork Delta is something to worry about. I see, many people here are using it to sell their tokens right after they received it especially bounty hunters.
They sell it in a low price and synonumously dumping their tokens even if they know it is promising in the future.
Another thing I see is that, you need to import your private key which I find unsecured.
That happens with the whole of exchange sites when bounty hunters are getting their pie and the price will be dumped to make them all sold their coin cheaply. And after all of their pie have already sold on the cheap price and then there will be a pump to recover it.
