BTC vs ETH = decentralized vs centralized
Satoshi has disappeared, while Vitalik is still behind ETH. And I'm confused

why smartcontract-based DeFi tokens dare to call themself decentralized while tokens can be locked at any time and even renewed by the developer as in the case of the kucoin hack.
How can you sure if that can be locked? The locked function can be added by the developers. Ethereum foundation has nothing to do with the implementation of the smartcontract whether the developer who has made the agreement with the smartcontract has already put the back door or not.
You should not blame that if you didn't know how it works.
The decentralization came from the network that has been running by a lot of miners.
