It can be fun trading for example after they have pumped DOGE and XRP. I missed the XRP one completely. Trading is very time consuming but can be very profitable. I personally enjoy more doing research on twitter, whitepapers, the discord groups and maybe the Telegram to get a feel if I am interested in a project and see a chance for its succes. Doing research on crypto projects and joining nice communities can be a lot of fun in my experience.
