I'm away from home for a couple more months. I did the math and I really have to go for something like - Bitmain Antminer S21 XP (270Th) ~ 6000$ in order to be in profit since electricity is not very cheap where I live. I am also thinking about partly solar powered solution where I will not depend on electricity for profit, but should start with a lower Th miner. I will be spinning a full-node first thing when I get back and then see how it goes
