What's going to eventually "kill" Shiba Inu are the high gas fees of the ETH blockchain. It would've been better if developers made a blockchain of their own for SHIBA in order to provide cheaper fees and faster TX confirmation times. Without its own blockchain, the token would be subject to the underlying blockchain's limitations. The problem is not only the gas fees, but also the large supply of tokens in circulation. There's "hyperinflation" "baked" into the token itself. ..
I don't invest in meme coins, but I still have to admit the obvious that work on own blockchain is underway and we will soon see the layer-2 solution - Shibarium. Also, a mechanism for burning tokens has already been launched, which, according to the developers, should lead to a reduction in the supply of Shiba. That is, developers see vulnerabilities that can lead to the collapse of Shiba and try to eliminate them in their updates.
