I’ve got an AvalonQ sitting behind me at home. 93TH/s. It’s a very affective space heater lol. Probably overkill for what u want. But I’ve recently bought 10 S21 Pros with a hosting solely for the purpose of stacking non-KYC stats for a future emergency :). Currently stacking around 2.5m sats per month with this setup. If u can afford the capital outlay (I do it in my retirement fund), it works out to around $90k to mine 1BTC. I suppose it depends on your core reason. For me, it’s an insurance policy.
