I'm usually a holder I still coins and tokens I've got from Bounty campaign just like the two of the just recent projects I've participated in I'm still holding both of them but there are instances in the past that I dump my coins/tokens because
The coin is not progressing and I want to buy coins that has more potential.
So what is or are your reason why you are dumping your coin?
I always try to hold my coins and constantly monitoring the market if this is worth to hold or not before I sell it. But if the project is promising, then I choose to hold the coins and wait to have a good profit from it.
