All old privacy coin did not surpass ATH but other old coin like BTC, ETH, DOGE, CARDANO did it, although the total marketcap surpass ATH in 2017. This is because the money from investors flow to others project like DEFI, Smart contract and NFT project. In my opinion NFT and DEFI is more powerfull project than privacy coin because crypto community get more benefits from it. And for ecosystem of smart contract platform also keep increasing even with so much competition in the market.
