Thank you for all your responses. This site is as i remember it, great with people helping each other. I must admit that I have felt like mining again, hehe
I saw hashnest is closed, so no way to mining again. In Spain, electricity costs so much now, 0.25€/Kw, also i saw my well aprecied colos at Cryptoboreas is closing, too, so i think i will stay out for the moment. I have 2 friends doing something with cryptos, so i will have an eye here hehe.
Thank you all!
Unfortunately, the only true cloud mining, i.e. the Hashnest, no longer exists. They mentioned that maybe they will come back with a similar project, but as far as I know, nothing is officially known for now.
Hundreds of other cloud minings have appeared since 2016, and they've all turned out to be a scam, so don't be fooled if someone offers you easy pasive income.
