I am sorry to hear about your loss, @belhejna.
I agree, their contracts make their profit guaranteed not the investor.
BTW, my contract does not have the profitability condition
Did you find a better option for mining?
One friend suggested GiggaWatt.
Sure, they are selling shovels in the new Gold Rush.
I starts cloud-mining BTC last November. Now, returned more that 200%, but mostly due to price appreciation. If the same amount of money was invested into BTC at the same time being, the current returns is about 41%. Difficulty increase with appreciation for sure, even if you have your own hardware mining.
Forget forever terms, mining hardware obsoletes (return rate < electricity price) for probably less than 1 year if the crypto mined are profitable and appreciated.
I am on the break now with any mining. I started with GR mining which unfortunately was a scam and was happy when found Genesis thinking they are fair. My current strategy is buy and hold (I am really not the only one:-)) ) The only pitty is that I didnt start this strategy 2 years ago with my firts BTC:-))
I get your frustration with mining. Holding BTC is still a great strategy.
Not that frustrated:-) I will chececk this GiggaWatt:-))
