Fluctuation of the Market is always followed by uncertainty, confusion, or even panic of investors. What you need to at that time is to keep your head cool and be patient.
patience is the key to keep your cool, being out of yourself and being impatient results of panic selling. the only thing to avoid panic selling is to stay away from it for a moment until its recovery.
once we become panic, we cannot think about preventing the loss and we can decide what we need to do, the only one things that we know is how we are not getting more lost. this will attract us to sell the coin we have without realizing that the chance for the coin to increase is still wide open. not just ethereum that is fluctuated but all coins in the market have the same things and we need to understand about this so we can use the next strategy we have and we need to have a backup strategy if something is not working like we predicted.
