I have less than 12 coins and at this current moment I wouldn't dare to sell even 1.
At this current moment the upward potential by far outweighs the chance of buying in a tiny bit cheaper along with the chance of missing out and/or having to panic buy back in at a higher price.
Also you don't lose money unless you sell at a loss, by holding in a small temporary downwards movement you don't lose anything.
We just broke 2 year bullish trend, have no buying power visible and also good news don't effect the price at all. We didn't have a bad news for a long time, we forgot the feeling... If anyone sold short term (weeks) be careful for high up volume, otherwise not so so risky. There won't be moon here next week.
