Bitcoin is essentially built with one goal in mind which is a digitalized P2P currency. Ethereum is a platform, not only a coin.
Ethereum is intended to facilitate immutable smart contracts which has has very broad implications and use cases. We've already seen companies like Amazon, IBM, and central banks experimenting with it.
Super excited to see Alchemy launch publicly. I was part of the early team before leaving in December to start a new startup. If anyone has questions, I can ping someone on the team!
