I’d go with the former. The latter is literally just a job. An extremely repetitive and pointless job. And from what I can tell from spawn probabilities after considering the time you’d need to spend playing the game enough to keep mining, we’re only talking 3 or 4 diamond ore blocks per hour max so like 100k annually as a full time job. You could do it as a part time side gig but by the time you hit the 100k from choice 1 you’d be chasing the compound interest.

Edit: oh it says $1.5 not $15. Make that hell no then
