As far as I know, it's one of the bests (if not the best) cloud mining platforms.
The last time that I checked their website, the SHA256 contracts were out of stock, so I didn't purchased anything.
If you finally invest, I recommend you to stick with the lifetime contracts rather the ones with an expiry date.
But if you ask me about the best option, I would invest directly into Bitcoins rather than mining power. For me isn't worth the wait until recover ROI.
Just my humble opinion.
Have a nice day :)
I have been using 1-hash the last three weeks and it seems legit so far. https://www.1-hash.com/ref/USR92929
Maybe I will regret it in the long run, but so far I am seeing it work as advertised and have made several additional deposits....I started very small with $50 USD.
I use hasflare.io. Genisis was sold out. Been doing it for a week now and am happy with it. My strategy was to make my initial invest, 60% into coins for hold and put the other 20% into mining. It has an ROI as long as bitcoin doenst crash, so I think it is a good investment.
