The yearly yield of the trader is optimized by performing simulations with real historic trading data of Bitstamp (> 12 million trades).
The trader will only sell bitcoins when a profit can be made. The strategy to sell only with profit assumes that Bitcoin price in the long run keeps rising. Therefore the trader can wait until each pocket can be sold with a profit. This means that in a long lasting bear market, in a worst-case scenario, little to no yields is made.
The yield of the trader depends strongly on the market. When the price of bitcoin fluctuates strongly the trader makes the best yield.
