Cloud mining is not profitable.  If it seems like it is, the company will disappear with everybody's money after 6 months and there's nothing you can do.  After all why would somebody go through all the work of setting up miners, a website, and company so they call sell you profit?

Miners don't cost 100-200k in USD. You can buy small ones for as low as $50.  The large companies do have a benefit when buying millions though.
