A profitability calculator on your website would help. The page here: https://portal.rentaflop.com/blog/hosting seems to imply that you are taking a cut from the regular ETH miner embedded with the rentaflop worker. You mind want to rephrase so that it's clear that:

- Your are offering a miner software which will occasionally work on blender renders which are more profitable to the miner than regular ETH mining.

- That your miner does not take a cut of the ETH mining part of the equation.

The idea is pretty cool though! The timing is simply unfortunate as there is a significant increase in (probably rightful) crypto skepticism right now.

Best of luck!
