i still be able to stake?and run a validator?
Yes you will be able to stake. I suggest that for the second question you go to Oasis discord server ask over the 'node-operators' channel
Yes, as Vic mentioned above you can stake with ledger. And coming to the running a node I'm not sure you can use ledger for that but most likely you can. Still I'll ask with my team about this or you can hop on to our Discord.
