Great list so far. I like your parameters for deciding but believe in the future a select few things may start out centralized and become decentralized over time. The one example I can think of right now would be Decred. It's understandable why it didn't make the list although I think at this point it is actually far more decentralized than some of the coins listed.
From
here it seems like Decred is semi-centralized.
- Monero (traded on Bisq) YUP
- Ravencoin (tradable on BlockDx, traded on Crypto-bridge) PUMP AND DUMP
- Dogecoin (tradable on BlockDx, traded on Crypto-bridge) MEME COIN
- Namecoin (tradable on BlockDx) HUH SAY WHAT
- Terracoin (tradable on BlockDx) SUPER LOL
- Grin (tradable on Bisq) LOL
- Aeon (potentially tradable on Bisq) DEAD
- Peercoin DEAD
- Slimcoin DEAD
- B3Coin DEAD
I understand your point, but we need to research basing ourselves on criteria.
For instance if Raven is a pump and dump coin in your opinion it doesn't make him centralized basing on the above criteria.
The same if we consider Dogecoin a Meme coin.
However I think that to avoid mentioning dead, dying, very young coins or coins that are not finding people's favor at all we can introduce 1 BTC/day trading volume criteria.
That's why I have to exclude Terracoin, Slimcoin and B3Coin for the moment.
