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.
You said it well enough honestly OP is right it will be easy to hold some small amount of shiba for future sakes, I would only get worried if my buying is up to 500$ or 1000$ but anything below 200$ is something I can give a shot and hold for very long time, it really won't hurt 😉
