As crypto becomes more and more centralized with the tools that traces out who is depositing and who is taking out. It is getting harder at levels of swap and the banks for those who take funds out. And in order to get over this issues there are some of the efforts being made be it XMR and other privacy benefiting coins. 

In case of Ethereum there are some of the layer 2 solutions already. Like Polygon, optimism, ZK all of them have the privacy layer and more of those are likely to integrate with projects like agglayer too. However some protocols are coming out which would offer more security and privacy for big investors. 

This protocol has three layers : contract layer, zero proof layer and associated layer. These layers collectively make it easy to keep your payments secure and private. And it helps especially for stablecoins and the bank swaps before they reach the account. So this is especially handy if people of those type keep the funds in the decentralized accounts. 

Say in some banks and the investment path, you'd be enable the protocol pool, where you can make full or partial withdrawals and get paid with privacy too. It supports the native tokens and the ERC20 tokens too. Users control the funds as they are part of the non custodial pools and they can easily get it out if the funds are not approved. 

Ethereum has managed to hit more tech triggers than Bitcoin. I am sure privacy and the ability to have more control over stake would make ethereum as future investment. There would be value generated out of the same but it would take some efforts and time to get things right before we can accept it like bitcoin in the govt around the world. 

Let's see where protocols like these land up. You can check out here.
