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.
The problem is the airdrop participants have no choice to use another exchange site. Usually the crap coin will always be listed on the crap exchange site and this is a common thing.
I know that's the risk that the hunters must have deal to be able to sell their money. The problem is on the project and exchange site that already listed the token.
