I've also had that kind of experience with other coins. I used to hold a lot but got impatient and ended up selling it before it boomed. That was really regretful yet served a lesson for me. Both Shiba and Doge has a huge potential but holding these coins really needs patience especially if your target goal is good for the long run. As of now, Shiba needs more improvements and adoptions that will have a positive impact on the coin.
