There are many variables to consider when we are trading digital currencies because if you are trading coins pegged to Bitcoin and the Bitcoin price has some sharp falls or gains, then your price predictions for a specific currency and your chart reading may not be accurate and you could lose or win big. We can only try our best to minimize risks and set certain parameters for buying and selling, along with having a calm mind and also being patient. Sometimes though we need to initiate small losses in order not to lose in a big way, or take shorter gains to minimize risk.
