XRP is special in that it's distributed, but I wouldn't call it decentralized (so you're completely correct in calling it a crypto with a centralized authority)

XRP is special in that it's distributed, but I wouldn't call it decentralized (so you're completely correct in calling it a crypto with a centralized authority). For instance it's possible for nodes to block other nodes at their whim. This is a very attractive trait for banks or groups of banks. But similarly it's a very bad trait for any smaller actor. So sure, it works, but it also gives up huge amounts of control to central authorities. I mean, if you're OK with giving up your freedom to uncontrollable inflation, then go right ahead and use it!
