I take almost all of my fake government currency and convert it as soon as I receive it, so I barely have any left at all times. So it's not like I'm losing Monero by paying my bill. I'm just not gaining it as fast as I otherwise would, because I have to pay for my bill in some way or another, and I'm just choosing to pay for it in Monero. As I said, I treat Monero as money. Therefore, if I need to pay a bill with it, I pay the bill with it. But I always, at least, replace it, if not get more than I used to pay the bill with. The person who spent 10,000 Bitcoin on a pizza in 2010, for example, the problem wasn't that they spent 10,000 Bitcoin. The problem would be if they didn't replace the 10,000 Bitcoin they spent with 10,001 bitvoin. Then they would have had even more Bitcoin than they started with
