I use eobot and nicehash and they work well. Nicehash is nice since you borrow someone elses hashes. I like that you can sell back your hashes by trading them so it gives ROI more easily. I know there have been many scams but you can easily check by using a mining calculator. So if their rate is better then the calculator then you know something is wrong.
Yeah 2 cloud mining has an excellent performance and healthy. 2 cloud mining is still standing and has no problems. But I'm not sure that it will always survive, because all the things that exist in the cloud mining will definitely have problems. From the start the tools existing funds, mining, or maybe they're wearing something that is not supposed to be used
their are some people have investment at their and their feedback is really half or shall we say there are telling bad and good, but for me cloudmining is done on my system and i cannot trust them anymore since that business are in horrible state where we cannot guarantee to earn our profits for certain time, and so by that its really better to find. another thing that we can benifited the most.
