What would be the definition of a good coin? With just under 20 000 coins/tokens listed (CMC), do you think 1% has any purpose and meaning? Those projects that have the most money and the most capable teams get the most visibility, which means the most investment and some kind of false credibility.
I believe he refer to top 10 or 100 coins on CMC or Coingecko that considered as good coins, while the fact they're list only based on the market cap, not from the usage. It's shame how XRP aka 100% centralized coin can get back to top 10 coins, there's other coin is more deserve to reach top 10. All coins except Monero and DAI are completely useless or copycat.
