To the extent that I can, I already hold most of my crypto in private wallets... old habits... although, some of the alt-coins are a right pain in the @!#$@ to keep in private wallets (plus, I'm not always sure that their software is secure), and so I do leave some of them sitting on exchanges... but for the most part, I have it out. That said, I do need to go through and do some tidying up...
