Well, you don't have to have a standalone coin to get the features you desire. For example the AZTEC Network, which is a privacy protocol, can be used with any Ethereum-based ERC20 token, including algorithmic stablecoins like DAI, and soon Reserve.

A demo a couple years ago showed AZTEC being used to conduct privacy-protected DAI transactions for the first time:

Since then, AZTEC's privacy technology has become more efficient in terms of gas, and more effective at protecting privacy, going from protecting merely the privacy of amounts, to protecting the privacy of amounts transferred and sending/receiving addresses.

AZTEC is also developing a zk-Rollup, which increases Ethereum's maximum throughput from 15 tps to 3,000 tps, so that these private stablecoin transactions can be done at scale (though not 3,000 tps, since privacy comes with a computational and state storage overhead, but still much greater than 15 tps).

/s isn't that Zcash ? the price doesn't change much. /s

Zcash will be adding support for user defined assets. may be some one will create a stable coin based on Zcash using this.

Monero is on its way to being delisted from all exchanges, and outlawed.

Mister, we have “xUSD” !!! It is first and only private untraceable stablecoin math backed on $XHV blockchain which is fork of $XMR. See www.havenprotocol.org

Haven Protocol’s xUSD is what your’re looking for. The potential for this one is huge. Just check havenprotocol.org or join the discord server. Very active community and really exciting stuff to come such other xAssets including gold, silver, euro and Chinese yuan, all with Monero tech. Twitter is @HavenXHV. Cheers.
