Hey, someone told me hashnest is the biggest scam site, why would they say that if it wasn't true?
I guess that someone was trying to get you into his own pseudo-cloudmining scheme. Hashnest is owned by bitmain - the company that produces mining hardware of their own. I'm not advertising anything though 
Most likely this is true. Look into some of the accounts that push some of the crap scam cloud mining sites. The only cloud mining site I would even send people to is hashnest. It just is the only one around with the legitimacy.
That being said I personally would think about buying a miner and looking at hosting as a option. I just like owning the hardware as it gives me something to sell at the end. Which can be a nice little bump in ROI.
