If I end up using Exodus wallet to manage BTC and XRP, but one day, Exodus decides to get out of the business and shutdown, will their wallet still work?  From what I can tell their wallet seems to be a hybrid personal wallet but requires you to be online to function.  Is the need to function driven due to the need to sync with the blockchain and if yes, does it sync with nodes on the network or does it need to sync with its master node that it manages that could become offline if it goes out of business.
