The company owns numerous selected mines in places like Canada, the United States, and Kazakhstan
Did they prove any ownership on those?
and they have a comprehensive rating system that includes site compliance, power stability, quality assurance, the scale of the mining farm, and the fund guarantee to ensure the compliance and stability of the hashrate.
I do see they have very professional advertisement writes. I couldn't have been writing more legit-looking nonsense myself.
Now the real question: did any real (and preferably trusted) person managed to actually withdraw from there? Because that's the only real test, all the rest is sophisticated blah-blah.
