Who told you that mining have no risk? That's wrong information, imagine buying a rtx3070 for 1400$ for mining today and tomorrow or probably two weeks later bear market starts you won't be to make your ROI back, oh yes probably in 1000 days later and that's even if your electricity is free
Depends on what kind of risk you refer to.
From your example, if the bear market starts, what happens to his investment? Will he be able to make his ROI back, ever?
As I said in the previous reply, when investing in hardware, at worst, he still has a hardware that can be resold (with a lower price, of course).
When investing in a market, especially in some highly speculative asset, he can literally be left with nothing. So, yeah. I still think investing, without prior research, is far more risky than mining.
