Track coin value by % not $ on your computer or phone app. Tracking your balances by % vs $ is very helpful in the way of not rocking your emotions with large numbers good or bad. You need to keep your emotions solid and treat this as simply numbers. I have a much easier time being able to not dwell so much on the dollars but look at the big picture or %.
Try % not $ and let me know if you feel more stable in you decision making!
