Do whatever you want with it tbh.
If it's worth transacting (high value of token and not too much in fees) then I'd move it to the ledger and use mew - they're not too different anyway.
Ok. Do you have any thoughts on why all ERC20 tokens aren´t added to Ledger (Live) by Ledger? I find it messy to store different ERC20 tokens in different wallets.
