Can you post a video of a miner at work and add more transparency? Not just a small tablet viewed there in the corner, where one cannot understand what is on it. A video where one can see it at work on a pool, making actual money, having shares that are actually accepted and paid for?

Alternatively, what is my protection as a buyer from being scammed? Bank transfer, bitcoin... etc, all one way systems with nothing to protect me from a scam (I am not saying you are a scammer, but that does not guarantee i will not lose out. Does it ?)

Looking forward for your reply
