Hold when the market conditions are dropping like now it is certainly better than selling, I bought EDG a year ago and still hold it until now, hopefully this year's price can reach at least $ 1 by the end of the year.
Buying some cheap coins at this time is a good decision to hold it for a while and I expect it will be back at 1$ in this December after some new updates released out . Don't sell it now or you will be lost much.
