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?
Personally, I do not endorse KYC for bounty distribution. But this is necessary part and you have to do it to get your tokens. Of course, there is no an absolute guarantee that your personal information will not be leaked. But if you really care about it so you shouldn't participate in such bounty campaigns.
