I only have two wallets.
Working on getting a site working so I can have an online wallet to make payments over my phone.
I'm thinking about buying a USB JUST for a bitcoin wallet.
Then it will be like:
Windows 7 - No more than 10BTC. Used for forum transactions.
Linux (cold-storage) - No more than 100BTC, used for supplying my Windows 7 daily wallet.
Linux/USB (ICE-Random) - Anything than would get a monthly/daily payment.
Linux/USB (ICE-Frozen) - Majority of my BTC. Will take 100BTC each time from Cold-Storage to be moved here.
May seem like a lot, but it's to keep me safe.
