It's not only that Ripple XRP, is centralized, about 70% of the coins are out of circulation and are not being counted at the market cap, but they do exist.
Those coins can be released by Ripple Labs any time they want, so the market cap is way above from what it should be.
Ripple network wasn't made to be decentralized, and you can't actually connect a node to the network as you can do in the bitcoin network, only ripple labs(or those who got the permission from ripple labs) can run a node, it opens the netowork for variety of dangerous attacks.
Yet people keep buying these god damn coins? What the flying hell is going in here, I seriously don't understand majority of crypto investors, no offence OP (maybe some but you know I don't know you so none really
).
