XRP, as much as I consider it a centralized coin with a concept that doesn't really make sense, seems to have established itself in the top altcoin positions, just like Ethereum - it's one of the few coins never having fallen out of the Coinmarketcap top 10, since 2013. I think this is related to its banking-oriented ecosystem of users. I don't know if that will change eventually and if better, more decentralized competitors could catch up.
People think the banking deals settled by Ripple the company are similar to banks positioning themselves in XRP the token, but that's not the case. XRP is nothing more than a product without any purpose other than allowing people to move value quickly through its centralized ecosystem. If people like using centralized garbage they can just as easily keep using PayPal, and the best thing of all is that PayPal has no insane premine.

Ripple the company, or more precisely said, Brad Garlinghouse and his buddies, own 60% of all the XRP tokens in existence already (they are currently locked up). On top of that they also own the majority of the circulating supply. It could very well be that they literally own like 75% of all the XRP tokens, which means 75 billion of the 100 billion tokens.
XRP on average pushes through trading volumes of around $250 million per day, which is peanuts. Litecoin, which is less than 50% of its size, pushes through the exact same daily trading volumes. Even Ethereum Classic with a $1.1 billion market cap generates more trading volume. XRP is just one big clown show.
