Are you sure you have only done KYC in that bounty?
BCNEX is one of the bounties whose project namely exchange, becomes a scam.
Yes, I did KYC there, at first everything looked very clear and very convincing, that's why I dared to do KYC. But suddenly they turned into scam, now I am very worried

But until now there are still no complaints about the identity of the bounties who report that something is billed so I hope they are just a scam of bringing money and don't sell ID data on the black market, of course this will be a lot of worrying apart from BCNEX is a scam project until now.
So whatever the current bounty that is required for KYC, it is better to avoid it so that there is nothing to be desired considering there has been a lot of news about the sale of personal data to someone to be misused.
Previous bounties had many hunters doing KYC for just 2 cents.
