Even if indeed the Shiba Inu will undergo an update to become a privacy coin through support from the Bermuda dApp and the rollout of the Layer-2 Shibarium protocol. Although it is possible to convert ordinary coins into privacy coins, the impact of this change depends on the technical factors and features introduced by the coin project. Changing to a privacy coin does not guarantee a significant increase in price, as the value of the coin is affected by various factors such as market demand, adoption and investor sentiment.
Many privacy coins like Monero and ZCash have problems with regulators and delisting on the exchanges. It is hard to develop a coin which is privacy.
In fact if they had serious problems with regulators, they would not be traded on centralized exchanges. It would only be possible to buy confidential coins on a decentralized exchange. We heard many times already that all anonymous coins will be banned soon. But as we see they are still available for use.
