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 😉
As long as it's very good and you can do it, then there's nothing wrong with that, but why sacrifice on meme tokens whose potential is still very low when there are more coins you can buy for under $200 even though for you it's a very large size small.
