Hi,
I've setup an offline wallet at home in a VM with no networkcards. I have a few bitcoins in that VM and when I'm at home I transfer an unsigned transaction to the VM, have it signed, and use that transaction. This is usually good for small transactions when buying pizza or stuff. A few weeks ago, the bitcoin price changed and while I was on the road, I actually had want to sell a few bitcoins, but this was impossible since my coins were very very safe at home.

So i'm wondering how you all use this in a practical way. I usually kept for like 100 US dollar bitcoin in an online wallet for small payments. But if there is a big price change, I would like to be able to respond faster and not rely on my very safe offline VM. And I of course don't want to store too much money in an online account.

Any tips?
