- What would be better:
a) raspberry pi 4b with 4gb or 8gb ram
b) the new rapsberry pi 5 with 4 or 8 gb ram
Does it make a great difference on which rapsberry to use or only on which usb miner?
RAM matters little when mining on pool. But some people report Pi 5 has more stable power supply/voltage.
- what would be the ROI?
Let's assume i would buy a pi 5 (about 100€), usb hub, a solar panel and 4 of those usb miners (one costs ~200€)
Nobody knows since you don't mention your electricity rate and which GekkoScience you plan to buy (along with it's price).
