In general, and because the return is small, any attempt to manage returns using any decentralized network, no matter how cheap the cost, will end with those profits being lost.
If the site is reliable and offers a lightning network withdrawal service with a team that monitors scam or phishing links, I think it will be successful.
Idk almost all ethereum dapps work like that.
Yeah return is small, with current minor tasks you can earn about $20. It's not much but those who are trying to wet their feets in crypto, could be helpful.
You can only withdraw to wallet which you login'ed with plus is there lightning for ethereum?
