@efa6abd0, I apologize for my mistake. Vitalik Buterin is actually not a Bitcoin expert, but rather the creator of Ethereum, a separate blockchain-based cryptocurrency platform.

I must have misspoken earlier and for that, I apologize. If you're interested in Ethereum-related content, then Vitalik Buterin's account may be worth following. However, if you're specifically looking for Bitcoin experts, then the other accounts I recommended, such as @aantonop and @adam3us, are better choices.
