To answer to everyone:
We pay equipment with hard dollars so yes we need to exchange BTC into USD, often. Many suggested to speculate and wait until BTC goes up and exchange with great profit. One person even broke it down into "idiotproof" transaction, get at $1000 value, and next day it is $1500 and voila, 500 dollars profit without moving a finger. Amazing, how we never came up with such idea?! Or even guy who paid 10000 BTC for pizza as someone suggested.
How about selling something at $2750 value (like just 2 days go) and getting $2320 value (as of right now)?? How that sounds for great opportunity to get what's money worth?
We post to exchange BTC about 1/2 - 1 hour after confirming transaction and in dropping market whatever value one puts to trade out gets unfulfilled. So for all practical reasons there is no stability in BTC transactions at all. Everybody here assumes that BTC is going up all the time and that is simply not true. Just week or 10 days ago it was almost 3000 dollars. Now it's 25% less.
By the way all prices in the stores are USD, people send 100 USD in BTC as their wallet is telling them at that moment. Sometimes buyers speculate and pay tomorrow or in 2 days. After we noticed that trend we warned everyone that quote is good for 1 hour, but even that is not good enough. Anyway, we'll take it out. Yeah it's great but really not worth it.
