Hi everyone,
distributed ledger technology is the future, I think most people agree on this, but why bitcoin?

Bitcoin is the oldest system, it is not scalable, it needs second layer scaling solution, it is energy consuming, there is few big mining pools and is not very decentralized. There are other problems too.

Woudn't a 3rd generation blockchain that is more decentralized in practice, less energy consuming, cheaper, and offer smart contracts and many more possibilities surpass bitcoin at some point?
Is the first move advantage so big, is there something else I am missing?
