So, I was cleaning my electronic shelves and found several unused old Raspberry PIs (versions lower than 4). I've seen some people use them to mine or run a stake pools for BTC, Monero and such, but I was wondering if is it really worth it. Has anyone done anything similar and can share the experience? If not, I guess I will have to find another use for them. #rpi #raspberrypi #btc #bitcoin #ada #cardano #algo #algorand #monero #xmr #crypto #cryptocurrency
