I do a signature campaign right now and investing in coins that I think will have the potential to grow mostly new coins, it's a risky way to earn Crypto you need to be very diligent in your research, there are so many scam projects right now, but still, the best and profitable way to earn Crypto especially if you find a good project, I used to do faucets and airdrop but I stopped because it's not profitable compare three years ago.
