The problem is you are cashing out and not holding till market value comes up. Hold and that 2 dollars today 30 days from now maybe worth 6 dollars. Mining is not a get rich quick unless you hit the jackpot mining a coin with no value that goes to the moon. Just my 2 cents.
Exactly ... And it is moronic to track daily in fiat value even if you are not cashing out daily. The exchange rate to fiat is constantly changing.
Some people cash out frequently to convert to fiat to pay their electric bills..... I cash out 3-4 times per month just for that reason. Or once per month if the prices are good.
