I have a question I hope someone has already solved. On the exchanges decred(and all coins) are traded in BTC. When you are moving coins back and forth(some people call this trading, I call it losing) you have to keep track of the fiat price you buy/sell a coin at. With the volatility in coins you could buy decred at .0092 today then sell it at .0093 the next day and not make any money or worse actually lose money if btc dropped in price. How are those of you that trade keeping track of your actual cost/price for each transaction? I have been messing around and just using a spreadsheet to track my in and out price in fiat as well as btc.
