Ethereum is and has always been a virtual machine. It’s nothing like Bitcoin, although it has used Bitcoin code completely with lots of changes.
It’s quite easily programmable to create countless projects with their tokens on its network.
Bitcoin is solid and yet a bit rigid allowing to create infrastructure around it with the second layer (on-chain and off-chain solutions).
Next big thing? Well, it sounds like hot air. Next big thing would be something like “anti-aging pills” allowing a human to live eternally 😉
Bitcoin is the next big thing after Internet.
Bitcoin is Internet of Money. The infrastructure of “blockchain” projects are being built around it.
