As you hold- Do these things
I see many people and I have also advised people to hold as much as possible. Especially if you are not a pro trader. But there is one or two things I will like to point out.
Make sure the token you are holding still has a strong team and are interactive. Always check what is happening with the team. Sometimes a project can come to an end when a core team member leaves the team.
Regularly check the social media pages to see if team is making progress and interacting with members and also if they are delivering their goals.
Check their github to see if they are pushing updates. This is the most important thing. Check to see if they are actually building the future you are holding.
