Hi

I bought some BTC,LTC,XPR & XMR recently.. My plan is to keep them safe for a long time..

so i would like to store them on a cold storage wallet...

does electrum support all of these coins?
If not can you tell me what software should i use for each coins?

I don't need to make transactions very often so it does not need to be an advanced software..

I just the safest possible..

Plus,if my offline computer crashes.. what are my options to recover my coins?

Thanks!!!
