I doubt that Shiba Inu will ever be able to turn into a privacy coin like Monero or ZCash. Especially because Monero and Zcash are already better as they are and Shiba Inu is not really a coin but rather a ERC20 token. Which means it does not have its own blockchain, unlike Monero, for example. And as its on the Ethereum blockchain, it will never be an effective privacy token. Furthermore, I would stay away from any coin/token which is being held by Vitalik Buterin. He already sold part of his SHIB, showing everyone that he does not care about Shiba Inu, and recently he started selling tokens he does not consider "culturally or morally viable".

I am certain that its better to stay away.
