Hi folks, Super new to cryptocurrency -- just soaking in everything and playing around with a few small purchases. One thing I can't wrap my mind around is tracking % changed since I invested in a certain currency. I basically want to see what I originally bought it for, and what % I'm at, whether positive or negative. General rule of thumb is to sell when it hits 3-5% profit, but I'm not sure how to track that across everything and when I'm supposed to sell. the .000003 part if it makes it confusing for me to calculate. Are people constantly manually tracking it? Or is there something build into Poloniex? Thanks in advanced.
