FWIW I remember a former colleague who recommended it to me and his argument was about the cryptocurrency you “earn” from it.

I asked him if he could withdraw it. I asked him if he tried. He said not yet but he would. He came back to me few days later saying something along the line that “it’s not straightforward” which was a polite way to say he didn’t manage yet. He worked in IT.

To be clear I’m not saying it’s a scam or that one can’t use the crypto “earned” from it but at least back then, few years ago, some people were just riding on the hope, or even faith, that it would amount to something yet it seemed made in such a way to just hold.

So… not a scam but not exactly empowering users IMHO.
