shorts are happening a lot more these days because prices of altcoins including ethereum are falling hard and real traders don't hang around doing nothing hoping for pumps to make profit. real traders want to make profit from any opportunity they can get.
in a healthy market shorts and other stuff happen alongside each other. it is not a bad thing at all. and not to mention whether you pull your money out or not, they will continue happening. if anything the dumps will become more severe as more people pull out of the market as the sells aren't going anywhere.
