There's an easy solution to that problem: spend BTC when you buy things, and then every week-end, buy it back to get rid of whatever monkey money (fiat) people gave you (salary,payments,etc...)

That seems like a lot of work, but it's easy to automate.

And if enough people do this, this will strengthen the BTC economy and weaken fiat, so you can feel good about yourself when you go to bed.
