I see a lot of centralised digital currency projects gaining traction in the current bull market.

The innovation of Bitcoin was the game theoretical incentive of mining to teach consensus on blockchain state. It would cost you more to attack the network than to cooperate.

The whole value add over traditional money is the decentralised nature of cryptocurrencies. For code platforms it is the potential of fully autonomous apps that operate as long as people are paying for their use without central control.

It is sad to centralised chains take off such as the Binance Smart Chain that runs on delegated proof-of-stake on just 21 validators picked by Binance.

You are just playing with someone else's funny money that they control.
