Yes Airdrop and joining Bounty are not risky. All you need is hard work and patience. But of course there is a risk here and it is a scam of bounty. And when scams of course you will not get paid.
there is one more risk of theft. besides about projeck scam i myself often see people who are sad because their wallet hit by hack. so I also need security in looking for bounty. wallet security is the main thing
