Everything about holding and selling some certain bounty projects token depend on many factors, and a decision to sell or hold after distributions is based on my researchs. In my opinion, it very good idea to hold some good project coins/token if you have a thorough research about some of these projects that has very good user cases, good team, excellent marketing and partnership with relevant organizations.
Aa for me, I will definitely sell a token that I considers pump and dump token and move on.
