Are people still renting cloud computing Power to mine Bitcoin? A brother from another mother told me this and I said its impossible because I knew they are not profitable anymore, I might be wrong, who knows? That's why I need to ask fellow bitcoiners on this forum.. Is this still possible today? Where not even 20TH is no more profitable, or people are doing it illegally? Because the way he hyped this I am having a second thoughts maybe its illegal.
Mining bitcoin is not possible on CPU or GPU. This being said, one cannot meaningfully mine bitcoin on cloud computing / AWS like machines.
I don't know how is it for altcoins too, some can be mined with CPU/GPU and then converted for bitcoin, but you may want to ask about that on the altcoins area.
I don't think it's legal (the cloud website might kick you out) or it may not worth it (too expensive), but I don't know.
On the other hand, beware of cloud mining websites. Those are plain scams.
