When I started gambling with bitcoin a couple of years ago the price was always around $200 and it didn't fluctuate much during the first year. When I wanted to place a bet I knew 1 BTC was roughly worth $200, which made things easy. The price has being going up and down so much in the past few weeks, I'm never quiet sure how much I'm wagering. Three weeks ago I bet 0.5 BTC thinking that as worth about $700 but when I checked the price after I realized that I'd gambled almost $1,400. Thankfully I won on that occasion but I just want to warn fellow gamblers to check the currency price before you wager as it can fluctuate by $500 in a single day.
