Jason Langis grew up figuring out games. Now his son does the same, in worlds with their own markets.
“Observe the system, test an idea, notice what changes, try again.” That’s where better questions about money start.

How did you first hear about Bitcoin?
Tell us your story below. A friend, a podcast, a news headline?
🎃 Halloween, 2008: Satoshi Nakamoto shared a nine-page paper called “Bitcoin: A Peer-to-Peer Electronic Cash System”.
It turns 18 today. Still short, still free, still the best place to start. Have you read it?

Lose a game account and you can call support. Lose your bitcoin keys and there’s no one to call.

Answer: A, the difficulty adjusts. Every 2,016 blocks (about two weeks), Bitcoin checks how fast blocks came and retunes how hard mining is, so blocks stay near one every 10 minutes. No one has to vote on it.

This week the network made mining about 6% harder to keep blocks near 10 minutes. #Bitcoin

You spent months earning a digital item. Tomorrow, the server closes. What do you still have?
Before calling anything yours, ask: who keeps the record, who can change the supply, and what if the operator disappears?

🔐 Rough month for wallet security news: tampered devices sold through resellers, and fake “recall” emails asking for seed phrases.
The basics still hold: buy from a seller you trust, check the seals, make your own seed phrase, and never type it into a website. #Bitcoin
A new hardware wallet should arrive blank. If it comes with a seed phrase already written down, don’t use it.

Hundreds of hours of grinding. Then an update changes the drop rates, and your effort is worth less overnight.
Money deserves the same attention to its rules. Who can change the supply? What can you verify yourself?
