Wasn't aware of those ones, thanks. It's a shame they're not even in the top 100 by volume.

Ripple (XRP) has the 5th highest market cap and volume of any cryptocurrency, but it's very unpopular on a cultural level because it's basically centralized.

That's fascinating, I ctrl-f'd for Ripple on a couple charts since I hadn't heard of it and it wasn't on them. Do crypto sites omit it because it's unpopular or viewed as not a blockchain due to being centralized?

It's near the top on all of them, but you need to Ctrl-F "XRP".

Ripple has still the fifth biggest market cap.

If you look at the five biggest coins by market cap (excluding USDT which is just digital Dollar) then three of them use proof of stake, Cardano, Polkadato and Ripple. Ethereum is actively transitioning to proof of stake.

Bitcoin is the ONLY outlier. Though also the biggest market.

I'm old and clueless. Is proof of stake related to anonymity in any way? I read something about dealers in contraband switching from btc to monero among others for that reason.

No, anonymity for the users is generally separate from the consensus algorithm. XMR, at least when I was mining it many years ago, was more about preventing leakage of wallet, funds info to every person you transacted with - and is probably the gold standard in anonymous transactions - which is why it's price is so stable.

Ripple is not proof-of-stake. It uses traditional consensus with trusted validators. It's basically a fiat currency that is run by a corporation to benefit them.

Ripple (aka XRP) is number 5
