So the point is that Real Cloud Mining is Mining Rental that provides real hashrate with real hardware to use. And I got these words from miningrigrentals itself and they also emphasize the word "Real".
I wouldn't be surprised if people think this is just a semantic issue. At the end of the day whether you claim it is a real mining rental or not doesn't matter if the customer can't verify anything. I think as long as people understand the process whether the company calls it cloud mining or rental mining doesn't matter as much. It would be better if they allowed customers to verify their service such as giving details about the hash rate, mining location, power distribution, etc as long as it doesn't sacrifice the miners' privacy. I guess having a reputation helps to alleviate this issue. CMIIW.
