Hi,

i'm looking for someone who made some experience with btc mining using a raspberry pi and gekkoscience's usb miner.

Since i'm playing witht he thought to made susch a setup for myself i got some questions:

- 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?

- 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€)

- how long live such usb miners? (Livespan) like i don't have the money to buy 4 of them in once but i could buy monthly one new, but i don't want that when i buy a new one to "upgrade" my system i only get to "replace" my system since the last one just died.

- cooling system: what would you recommend? Is there also some rpi case for outside since i would use it with solarpower?

- what would be best practice to do this?

Thanks,
dissi
