Are genesis and hashflare trustable?
How made it untill at least break even?
To your questions:
1. Are they trustable?- Genesis ist trustable. They pay out every time, when the minimum value to transfer has been reached. In my case they transfer every 3 or 4 days to my ether wallet. They start transfering from the 2nd month on to get sure, they receive the price you have paid by credit card when you made the contract.
- About Hashflare I cannot tell anything. Ich wanted to sign a contract. To attract potential customers you can find a lot of discount codes, which promise you a discount of 10% or more. None of those codes worked for me. So I didn't become a customer of Hashflare. But as far as I've read a lot they should be trustable too.
2. Profit and Break EvenSee my calculation to
Genesis.
I invested 1000€ into a 2 years ether mining contract with 40 MH/s. After the first month I got about 0.65 Ether. It started with 0.029 on the first day. After 1 month I received about 0.017. Now after about 6 weeks mining I get 0.014 Ether. Based on this values, you can assume a diminution of about 40% each month. This means, after about 6 months the mining will become useless. With some luck, my revenue will be about 1.6 Ether.
Or more exactly: I bought 1.6 Ether for 1000€.
Dash (x11 mining) should be a little bit better, Bitcoin even worse than Ether. Independend on the current price and the performance of any coin, it's better to buy the coin you want than to pay it to a cloud mining company.
