Definitely I can recommend oneminers -
https://oneminers.com/ .
98% uptime so far. 7 Years warranty for miners and free repair for miners within 7 years warranty.
Basically they offer miners and have advanced managed platform so you can manage it from phone. (the majority of the miners are supported).
Now they have promo for 7 days trial - Time limited. Basically it is not a lot but you have free electricity for first 7 days

That is all.
The dashboard is quite comprehensive. Here is a sample:

They have hosting in Finland, Norway, Germany, USA, Dubai and newly Ethiopia.
The central they have in Texas - Austin and in Europe .
You can buy on their platform or also use their hosting and send miner there to manage it (it costs about 100$ per KW of the miner infrastructure fee) but you can super cheap electricity afterwards .
Looking at those figures, this can not possibly be Bitcoin.
As for offering 7 year warranties - that doesn't make any sense. Doesn't matter what coin you're mining, typical miners barely last 2 years (Bitmain) - maybe get 4 years out of better quality gear like Whatsminers, however no hosting farm is running gear that old as it would not be profitable. I'm sorry but your post stinks of scam.
