Centralized Decentralized Finance (CeDeFi) has gained attraction because of high Ethereum fees and fees at CeDeFi are low. A main player is Binance (BNB). But at CeDeFi, as an example for Binance, only a very small number of nodes (21) is operated by Binance and associated partners itself.
Nodes are elected by Binance Coin (BNB) holders where Binance itself is a very big holder of Binance Coins, so Binance has a very big power in electing nodes. It is very centralized.
For a satisfied solution, we should always choose Decentralized Finance (DeFi) over Centralized Decentralized Finance (CeDeFi).
Ethereum will bring updates for cheaper transactions in updates and later in Ethereum 2.0 and in addition to Ethereum we can use Avalanche, a scalable DeFi Blockchain where low fees, fast transactions and decentralization are even possible today.
Always use decentralized Blockchains (Ethereum / Avalanche) over centralized Blockchains (Binance)
