Not everyone is buying these things to get a ROI. I mine for the challenge of getting the best hashes from my hardware possible, and keeping my uptime as close to 100% as I can. It's a hobby. The fact I get some money out of it is a bonus to me.
Same for me! And its a way also to put your "money where your mouth is", to spend some good old bitcoins and to bring from the fiat into the crypto economy. Without mentioning that we are also running all the global finances! I trully think that its fascinating and makes a bit extra cash! I talk about this from the ammateur miner's perspective! I have trully found a beautifull vortex that has given me very important lessons about modernity!
Lets hope it all continues swell!
