several bounty projects, are now beginning to implement KYC on the distribution of their tokens
when I send my identity card is this safe? could it be misused?
We can't be so sure if your identity is safe or not. The moment you gave them your identity you have no control of it. I understand why you gave them your identity. You want to get the payment you worked for. But before giving them your identity, don't you think about if it safe or not ? How much you trust those persons?
Could it be misused ? BIG YES. Even though you do not have permission to them.
