For more space you can connect a usb drive with more GB !
Yeah, that was the economical thing (
that I'm talking about) on more storage needs to run more wallet on Pi.
Yeah i actually meant different coin wallets in one pi,
I read somewhere that staking two different coins at a time clogs the memory so it needs to be cleared time to time. Do you suggest a 64gb would be helpful?
That was enough, and then you can add more storage (
additional storage - the cheapest one ) You can use several basic OS on your Pi (
as above said).
