It is now a hyping token and its market cap is also very much. its true. But it is very difficult for $shib to take the top 5 position in marketcap. The hype of something does not last long. It has the potential to be a big dump like Doge at any time
In the top five there are a lot of good and strong coins to compete with meme coins like Shiba Inu, so that will obviously make it difficult to be in the top five for this year and not necessarily for next year either as the competition becomes more and more intense.
