No reason to paint with such a broad brush imo, I have investments in several other mining ops which remain profitable currently, one of which is possibly a scam but the others I have on good authority are legit and I don't just mean simply because they pay me. Why add more FUD? All it does it hurt faith in crypto overall from my view.. Hashocean was the highest paying site of it's kind which was a good indicator to me that they were a possible ponzi, but it is certainly possible to profit more than your average mutual fund by investing in a 3rd party mining operation. The math is not always impossible. I couldn't recommend a site to anyone else if they paid me to right now though.. don't want to be responsible for anyones money but mines.
