Many people have warned about it, it's best not to use small exchanges and never send money into it. Too dangerous
I Know it's too dangerous to use small exchanges as because they might scam. But for airdrop hunters it's not always possible to use known and big exchange like binance.
they can use popular exchange anytime . Persons use other exchange even its not popular because it will easy for them to use that exchange and maybe there are also other offer that exchange have that's why they use it.
I think its better to open scam accusation in that exchange its proven scam already if many members can withdraw their balance.
