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.
Yes, that's good money but in the modern world today, the KYC that you'll pass to them is that you'll never know if it will also be passed on to other companies that will market.
If you haven't noticed it yet, just you sign up to a website and then eventually, you'll receive various marketing spams that you have never reached out to them or even signed up for. Also, those identity that are passed onto them, they could be stolen and be on sale in the dark market.
Of course I understand that. But don't you pass KYC in order to trade on Coinbase or Binance? It's the same thing, after all. Today, these are the two largest exchanges with huge liquidity, DEX will not replace them, which means you will pass KYC anyway.
