I create a list of coins that are active and I am interested in, Most of these are very easy to trade and have great charts.. Its pretty hard to find bad charts in cryptos.. they are full of novice traders, so there easy to read.. but yes then I set alerts and orders in places that I would buy when a panic dive happens, then as soon as I have bought I already set up my sells up above where they should bounce to.. I often layer into a trade since I cannot predict the future.
