Hey guys! I'm realtively new to XRB. So far I've stored my coins on Bitgrail where I bought it. But I want to shift it to the wallet. I've a couple of questions about the wallet though:

1) Is the desktop wallet better or the online one?

2) Next if I store coins in the desktop wallet, do I have to keep my PC on, wallet open & unlocked like PoS coin wallets? Or is it like NEO's wallet which I can leave offline too? I want to avoid keeping my PC on all the time. Hence this question.
