I don't know guys, I think you are very strict on this topic. Yes, you will not earn much money there, yes, you may expose your addresses and KYC. But let's not forget that this is still made for beginners and those for whom even $20-30 is important. Study coins like GRT a bit, provide graph quiz answers, and get a couple of bucks, for someone looks good. We are talking about cryptocurrency as a world currency, and in many regions of our planet (unfortunately) even $20 is good money. And almost everyone can do it.
