Why would we need shiba to be private when we already have Monero and 0xMonero? What do they offer that is different or better?
They say that competition is healthy... that's how we break limitations, the desire for constant improvements and progress. And it's good to have an alternative, not to rely only on "one thing".
As for the Shiba Inu and the transition to private money, I haven't noticed that there is much talk about it. Maybe it's just marketing testing for now, polling the public and all that. We have been talking about private coins for years, and many think that they are the future, but for now, they are still far from popular in the "real world", people outside of crypto still don't know much about them. Many people outside crypto are still struggling to understand Bitcoin.
Many people still can't understand what bitcoin is and how it works, and instead of learning about it in detail, they buy altcoins they know nothing about. Worst of all, they just trust the first blogger they see and make purchases based on his recommendation.
