Trying to understand the Binance CMC index, I just learned that users can use it to track the values of digital assets and currencies. And the crypto assets in the index will be weighted and rebalanced every month.
But the link shared by jackg suggests that re-balancing will be done Quarterly
I however wonder what happens to stablecoins since most of them are in the top 200 and those coins that sharply pump and dump due to manipulation. Maybe they have some criteria to filter such coins out.
