You are right, @foobar123, on current market it looks quite risky. I would better go for Z9 - it looks so much better in terms of ROI.
Anyways, whoever holds/hodls crypto has same optimistic views, and there are millions of people like this, having billions worth crypto.
It's kinda the same - to hold crypto and to mine crypto, in both cases you expect rates to get higher. IMO, mining with on a most productive equipment in one of the world's cheapest places makes more sense than just hodl.
