Agree. The blockchain is the tape; amazing! I'm a bit late to the party, but have invested a reasonable amount into it recently. I'm on the side of ETH 2.0 and massive scalability and lower gas prices(even though I currently mine liquidity) so the true potential of smart contracts and DeFi can be realized.

The Ethereum docs are pretty great if you want to learn more: https://ethereum.org/en/developers/docs/ .
