Yeah I've been a big fan of XMR and ZCash in the past. I'm kinda with you guys on XMR but I've read recently that in the United States, the Internal Revenue Service (IRS) awarded +$1M to blockchain analytics firms Chainalysis and Integra FEC to break the Monero privacy system. Who know whether they'll succeed or not but it's something to take not of. This is the article I'm referring to btw:

Have you guys heard of AOS? It's been around for about 2 years now and they've just released the AOS 2.0 roadmap which looks pretty exciting. It's not on most people's radar yet but it has zero-knowledge proof programming that's much more efficient than Zcash's or ETHs, smart contracts, 10,000+ TPS etc. I think tech and privacy wise it may leave the others in the dust.
Worth keeping an eye on but it's not on any of the large exchanges at the moment.
I hope XMR and the other major privacy coins stick around. Seems like they will always be a market for them, whether or not regulators like it or not, Lol.
