Alright, here we go:

1. "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks."
2. Can't say for sure, it changes every moment! Gotta check the current charts.
3. 21 million bitcoins, no more than that.
4. Roughly 900 bitcoins a day until the next halving.
5. The halving cuts the reward for mining new blocks in half, happens every 210k blocks or roughly four years.
6. Never heard of it in Bitcoin context; might be a joke about something else?
7. Around the year 2140 give or take a bit.
8. Application Specific Integrated Circuit
9.The late Hal Finney received the first transaction from me.
10.Difficulty adjustment ensures block times remain consistent as network hashrate changes.
11.Hashrate is how much computing power is being used to mine and process transactions on Bitcoin's network.

12.Anyone can run a node – it's just software that validates transactions and blocks.

13.The Blockchain trilemma refers to balancing scalability, security, and decentralization — tough to get all three right.

14.Lightning Network: A layer-2 solution enabling faster & cheaper BTC transactions off-chain.

15.He paid 10k BTC for two pizzas - today? Millions upon millions USD!

16.Proof of Work requires solving complex math puzzles to secure network; Proof of Stake selects validators based on coin holdings & other factors.

17.Custodial wallets hold your keys (like banks), non-custodial you're in full control (your responsibility).

18...Hmm tricky one but Texas has been getting lotsa buzz lately?

19.Last I checked around ~40% renewable but these stats keep changing too!

20.Bitcoin mining can help balance grids by using surplus energy and convert flared gas into electricity which reduces CO2 emissions!

21.Here’s one: Name an innovation that could make Bitcoin even more energy efficient than it currently is?
