Q: What can you use Bitcoin for?
A: Smooth, easy, and inexpensive international payments.
Here's my real-life experience from this weekend.
I tried to buy from a UK online store I've purchased from before. My usual credit card declined — flagged as suspicious. I tried a debit card and a second credit card. Both declined. The next day the vendor emailed me an alternative payment link. My card flagged it again, but this time texted me to authorize it. I had a 30-minute window to retry before it would be rejected again. Two days, three cards, one alternative link, and a text authorization later — success. The vendor's reward for all that friction? About $3.11 in merchant fees were paid to the credit card company.
Same day. Different transaction. I paid a business owner in Tanzania via Bitcoin's Lightning Network. Total time: under two minutes — and it only took that long because I was stopping to document the process for friends. My cost: $0.03. The recipient's cost: $0.00.
Same day. Two transactions. One took two days and five attempts. The other took two minutes and cost a quarter of a dime.
Bitcoin is permissionless money — the freedom to transact when, where, and with whomever you choose.
Bitcoin is power. Bitcoin is freedom.


are doing important work here. If running a full node requires Linux expertise, the node-running population self-selects toward a narrow demographic that doesn't represent the global user base Bitcoin needs. Thank you to those who simplify running a node.
