I was also surprised by their decision. as far as I know Kraken only selects good quality and proven projects. but their decision this time is very contradictory, they are listing the shiba inu which is a coin meme with millions of speculations.
Actually Kraken is also not wrong by including Shiba Inu on their list even though it is only a token meme, what is clear is that it is a worthy thing for them to do and basically the Kraken will also benefit like listing other tokens in the past
