Never heard of it but thanks for the heads up. The name "ExtStock" is like ExitStock, they've just removed the I.
Thanks but as I said I used it for airdrop purpose only. All my assets that was scammed by them was from airdrop.
I guess you don't have hard feelings for it but you still regret that you have balance there. Sorry for those loss although, it just came from airdrops still, that's still a good amount of spare money.
