Probably scam: minergate, cripterra.
Agree, even minergate is legit but the income isnt really great. And if you mean Crypterra then you must read on their own Thread, they use image from google.Question mark: crypto mining farm, 803 mine. I really dont understand them.
Cryptomining farm looks like not legit mining farm, they offer stable income everyday. Since the difficulty always changing but they has stable income. Really suspicious. For 803 i will skip because never heard about it.Minergate is legit and it's just a pool offering mining software a GUI on it. They don't even offer cloud mining or hosting of any sort, and I've mined with them and received payments from them in the past.
They offer Cloud Mining on their site
