Chia ROI is around 6-7 years if no hardware fail. That actually sux a bit lol. I have a small farm to play around anyways. I have replotted two times already.... still got around 30% of investment but it's just.... so slow... it pays my everyday coffee and nothing more but ok... just for the fun.
Possibly at current prices, maybe longer, but it depends on several variables: price of gear, electrical costs, and most importantly the future price at which you may or may not sell. That said, ROI is a terrible metric for anything crypto related. While it can entertaining and sometimes depressing, it's pretty much useless outside of that. You can use it to make a plan for selling or justify buying new gear or you can use it to impress your friends you can use it to impress the three random people still here (myself included). Since we're doing an ROI measuring contest, I'll slap mine on the table...I have no clue where I'm at. I know I've spent upwards of $1k but less than $2k. I've been at it since fall 2021 and sold about half of my earnings, to buy more gear of course, and have hodled the rest. I'm definitely not selling, especially not now, or at least I thought that was a good idea....you know, stick to the plan, blah, blah, blah. I've thought about dumping it and getting into some other shit coin that could go parabolic. Like I probably should've dumped it to buy WIF or Pepe or Bonk or Floki or whatever other meme coin....had I been smart, I'd be $50k richer right now. So here we are going from entertaining to depressing. From the above deduction, holding out for ROI is a sunk cost fallacy and trying to calculate it only makes me realize how much of terracore crypto is absolutely dumb money. Coffee does sound good though. Cheers.
