Good side: This site/bot have much real user and published only verified project (paying) .
Bad side: After joining a airdrop, participants need to pay fee to get there token and also participants not get all reward in onces . Participants get there reward by 2 step.
I Don't like pay reward for fee system. CZ sometimes the fee is higher than price of token.
I think buzzin need to Leave it for best quality marketing.
Firstly, the fee is not large; secondly, it is a guarantee that participants will not be able to instantly reset the token on the exchange after receiving it. Many projects are afraid to conduct airdrop for fear of dumping.
