Great post! upvoted and followed you. I also got scammed by some z-cash miner site. Therefore I decided to test and compare all the largest cloudmining contracts with actual proof of mining gear in a google sheet file. I regularly update it so everyone can get the best deal for their money at any time! I also describe all the criteria you should take into account before buying a cloudmining contract.
