Dont be. I still have a large portion and have not sold a single 1. This coin has huge potential to be above 10 BTC per SYNC. Normal markets go up and down and if you try to time it perfectly there is a good chance you will loose. Figure out if you think it will go up from here and buy. Once you think it is at it's highest you sell. Of course you will most likely not pick the exact bottom or top but give it time and if you have done research you should come out ahead in the long run.(Pending any big changes)
