I believe that these types of coins and platforms have significant potential to become increasingly popular as people become more aware of the benefits of privacy and decentralization in their financial transactions.
Furthermore, the community support for privacy coins is growing and becoming more vocal, with more and more people recognizing the importance of financial privacy in our increasingly digital world. This support will only help to further promote the adoption and usage of privacy coins.
Privacy coins have their benefits, but with governments in the way, don't expect such coins to experience an increase in mainstream adoption anytime soon. The only coins that will rise "to infinity and beyond" are those with a transparent Blockchain ledger like Bitcoin, Dogecoin, and Ethereum. That's because it's easy for the authorities to "hunt down" malicious actors on these chains, than it's the case with Monero or Zcash. Why do you think Elon Musk is "pumping" Dogecoin instead of a privacy coin like XMR? That's because DOGE isn't as rejected as XMR across centralized exchanges. Not to mention that DOGE is a "meme" coin that's often driven by hype.
We're still in a bear market, so it would be a great idea to accumulate prominent crypto coins just in case. Who knows what surprises we'll find in the next bull market run? Just my opinion
