That's really shocking to hear such kind of experience. Bitcoin transactions are not so long to loose money on the price difference and bitcoin doesn't jump from 100$ to 2500$.
I thought a business which based on bitcoin is developing very profitable from a day to day. I remember a story when some guys were selling pizza per 20 BTC each! I doubt that their business ended the same like yours.
If we sold something for 1 BTC yesterday and managed to exchange BTC into USD today we would lose at least 100 dollars. From about $2345 value it dropped in 8 - 10 hours to $2231. There is your answer. No business should be based on hopes and speculations that currency will jump up in day or two. Nobody can predict such movements with certainty.
Even more than few posters here said that BTC is not suitable to be form of payment but rather investment. That maybe correct so we are guilty of being enthusiastic enough not to believe that and think that BTC is perfect currency.
