In 2014 or something, I paid a smaller sum of money to some company called "Cloudhashing" or something, which claimed that I was renting part of their Bitcoin mining pool and all I had to do was to pay that little sum and then wait for the coins to roll in.
I never got a single satoshi, as you can imagine.
But ever since then, I've seen numerous services where you apparently can pay a large amount of money to "rent a miner" which they host/set up, basically the exact same setup as the scam I fell for. That is, I'm not buying a miner that they ship to me which I then plug into my own local power. I never see/care about the unit; it's "abstracted away" from me in the same manner that a "webhost" account is something abstract to me versus ordering a physical server which I keep running in my wardrobe.
It seems to me that it would indeed be possible for such a service to not be a scam. I mean, the argument usually goes like:
If they can just mine themselves and make more money, why would they sell this to you?
I get that argument, but at the same time, what if they don't have the money up-front to pay for that extra miner (or part of it) unless I give them my money? Does it not make sense that they use the customers' money to legitimately order more miners and have them set up in their optimized facility with cheap power and whatnot, which I could never do at home? Isn't it a much more efficient setup that I simply pay them to enable them to add hashing power and then both of us make money, versus me ordering a soon-outdated mining unit which I cannot run here anyway?
What am I missing? Are there non-scam mining services? I want to make Bitcoin but I'm not going to waste any more money on scams.
