I believe in cryptoCURRENCY, as people do pay extra for validation in currency. XRP and Monero are both designed for payments.
ETH, is being used as a currency, but this is a mistake. ETH is designed to run apps, and is doing that poorly.
I like the fungibility that Monero offers (making it similar to cash), but I just can't wrap my head around Ripple. I always associated cryptocurrencies with decentralized and trustless (at least at its core), neither of which seem to apply to Ripple. I would have preferred a "trusted party" system on top of a decentralized one to get higher transaction speeds, e.g. when the stakes/amounts are low.
If you are a programmer you will appreciate this. It explains the consensus protocol in detail. I found it fascinating: https://www.youtube.com/watch?v=w4jq4frE5v4
nolCoin is an experimental crypto-currency where anyone can make as many as they want for free (plus gas) but only in amounts of a maximum 255 at a time. then when total coins reach uint256 max no more can be made.
implemented as standard erc20 token, plus a make(address, amount) function you can use to create coins!
