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.
I do not see any problem here. If you got problem with the exchange, then just wait for the token to be listed elsewhere to buy or sell.
They sell it in a low price and synonumously dumping their tokens even if they know it is promising in the future.
How do you know that they know?
Another thing I see is that, you need to import your private key which I find unsecured.
You can simply use metamask extension if you do not want to import your private keys into their exchange.
