The Binance Defi Composite Index follows the defi-tokens of the exchange. It grew around 70% in a week. There was a huge jump in the total locked value in the defi-protocols, and it soared to near 25 billion from 15 billion USD in a really short time. Binance launched its index last summer, making diversification easier.
There are not so many indices in the crypto-industry, and there are way fewer in the defi. The own defi index of the Binance experienced a lot of interest, and also popularity. But it’s on a centralized exchange, so holding that, you have to sacrifice the main value offer of defi, the decentralization.
