Hi, i am a Linux noob and would like to know which Linux version should i start with my laptop if i want to run a Bitcoin node and various altcoin nodes?
Pros and cons pretty please.
There are none. Any version works. You should get an updated bitcoind and that probably has some dependencies that most distros should satisfy, unless you compile it.
I have nothing to say about altcoins but their requirements should be similar. It all amounts to what do you want to do with that laptop, because for the most bare needs you don't even need a gui (or a laptop, a raspberry pi or similar is good enough).
But anyway if you want recommendations, I'll say
MX Linux. Its currently no.1 on
Distrowatch.
Remember unless you plan to run your nodes pruned, they need space, LOTS of space, as in 300g or so for Bitcoin's blockchain alone and have the patience to wait for that to download. Pruned nodes will download the same, but won't keep the older transactions stored afterwards.
