Exactly like the title says!! I am looking to take some risks since I’ve been playing it safe my whole life…. I am 28M, I am looking to build a whole grid since I got a small extra room, so basically i want to start by buying the S21J PRO x 3-4 units and then add 1 or 2 every month to the collection till i reach 10 or so ( depends on the numbers ), I would like to hear some pros opinion in this. Am looking to hold that for 2-4 years or so.

Points: - Is it worth it since i am not paying electricity? - what exact miner should i get if its worth it - should i just buy raw btc instead ? - what are some points that i need to know about the mining life

All the best y’all
