As for cloud mining, yes agreed, we are actually removing that feature, it was originally part of one of the ways we helped users to earn earnings, similar to APY, but we agreed it was too complicated (hence why it won't be displayed on site soon).
You still haven't removed the cloud mining. This is a big No for genuine crypto investors when they see it, especially this statement "we also offer cloud mining to mine Bitcoin from your phone. "
We both know it's not possible for anyone to mine ETH using a phone not to mention BTC.
I will advise you to put a loyalty reward for users of your ecosystem instead of cloud mining.
Having said that, most e-commerce always comes from up to the bottom. What's the plan for your ecosystem to prevent this?
