Admittedly, #monero #xmr is not wildly popular because privacy isn’t wildly popular. But it’s not a popularity contest. If you want:
1. Default privacy
2. Decentralized
a. Over 11k nodes
b. CPU-mined
3. Fungible
4. Cheap to use (less than $0.01 tx fees)
5. Settlement w/in 2 minutes
…then use Monero. It’s untraceable digital cash, which some people don’t fancy.
