So the benefits of the Bitcoin Private is that it's controlled by central authority, has less security, single developer, no censorship resistance and no store of value proposition.
It turns out that it's competing for medium of exchange value proposition, meaning in competition with altcoins at this moment. And when it comes to the altcoins, most of them are fast with low transaction fees and similar business model.
And whenever Lightning Network will be adopted by wallets and businesses, the transaction time and fees will be better on the Bitcoin.
All in all not sure what are you so excited for!
