I have already written to bitmain repeatedly and they deny they have relationship with hashnest. They say they have "separated" from hashnest, that they are different entities, that I am complaining with the wrong company and that they can't help me.
So either they lie to keep my money or all the sites that say "you can trust hashnest because it's a brand of bitmain" have wrong information.
When were these info published? they could just be outdated.
March 2019 article:
Hashnest, a cloud-based mining platform, is no longer a Bitmain subsidiary but an external project funded by it.
and it's been two years since... they might as well not be funded by them anymore considering cloud mining is not as in demand as before.
In any case, it's best to get out of anything cloud mining. When things go south, it's highly likely you will be used to make up for the company's losses.
