According to CMC, there are 58 billion XRP coins in circulation compared to 19.86 million Bitcoin in circulation. I am not sure whether more XRP coins will join the already coins in circulation or not but one thing is clear that there is already a huge supply of XRP coins in circulation. XRP may be a good Alt like Eth or Tether as it's been among top 5 Alts on CMC for many years now but it's certainly not comparable with Bitcoin because of various reasons like decentralisation, coins in circulation and security.
Glad you've pointed that out. Yet, XRP fanboys are blinded by greed and will ignore the economic aspects of their "shitcoin". The fact that many are predicting XRP will reach $10 all the way to $100 is insane. Tells a lot about the ignorance of people in crypto land. We, Bitcoiners, know there's no other coin that can outmatch Bitcoin's level of decentralization and censorship-resistance. Added scarcity is a plus.
Who cares if XRP is faster and cheaper to use than BTC? As long as XRP remains centralized, it won't be going anywhere soon. A government crackdown or network takeover, and XRP will be done for good. That's why nothing can "beat the King". We'll see how long XRP lasts...
