You get paid by validating blocks, just like mining but hardware is replaced by required coins. and profit is determined by coin price in market.
Oh, it looks like we invest and they will buy devices to mine coins, right? Thank you for the information, I will take a look myself when I have a small asset.

You sound like need to get more knowledge about that.
