That's nearly always a bad idea. I never sell guns. I'd even sell some BTC before I sold any of my guns.

True, but I'm in Texas.
Unless you've got doubles of something that you just hate, or something silly you never want to shoot and isn't some kind of collectible, I still can't recommend it.
I understand the base elements, but this is a time based decision. I can always get another gun. If I can turn a $1000 gun into a $2000 gun via btc in 6 months, why wouldn't I? Especially if was comfortable where I was?
