What real user cases has Shiba ? It can be used for gambling and has fast transactions and low fees but that's about it. It is just a meme coin as you mention, nothing more. When we get another bull market, we will probably see some new created memecoins (and other shitcoins).
Besides that, Shiba Inu supply is too high and whales have too many coins under their possession, meaning on long run it's a terrible investment. It's not an advised investment for anyone in my opinion. All Shiba Inu has is powerful marketing and that is what has made many investors adopt it and still believe on it, although the concept is a total copy from bitcoin and dogecoin. Small investors should be careful, because as soon as Shiba Inu increases in price a little bit, whales will start dumping their coins on the market to make profit. For those whales it's a great deal, but for everyone else I don't think so.
If Shiba Inu had the scarcity of bitcoin, then it would be another story.
