Greetings Bitcoiners!
We've got a new time and day for our coffee meetup this month! We'll be at Denim in Mechanicsburg this coming Saturday, April 11th, at 8am. Although we've been doing them early afternoons on the fourth Sunday, we're switching gears for this month and next. Join us at Denim at 8am this Saturday in Mechanicsburg! We've also got a Bitcoin Pizza Day celebration happening on Pizza Day. I'll talk more about what Pizza Day is soon, for now just giving a heads up about the event next month. It'll be 6pm at Ever Grain on Carlisle Pike, Friday May 22nd.
I learned about a new website this week, am-i.exposed. It's reminiscent of a website that the Samourai team used to run, oxt.me, which is no longer operational. Both are enhanced bitcoin block explorers that offer insights into transactions beyond what others offer.
Bitcoin privacy is its own tunnel within the bitcoin rabbit hole. Although bitcoin addresses aren't linked with an identity on-chain, someone with information about a transaction obtained outside of the network (i.e. from exchanges or merchants) can discern which addresses likely belong to whom, and make inferences about other addresses that belong to that same person. Since the ledger is publicly available, and forever, it's a smart idea to develop good hygiene when making bitcoin transactions. Much like you wouldn't want you bank account balance printed on your t-shirt, or your 401k balance on a bumper sticker, it's good practice to keep one's financial info to oneself.
The number one rule: don't reuse addresses. Although an address can be reused, it's very bad practice, and modern wallets avoid it by default. Some who stack sats at an exchange might give them one address to send withdrawals to, never update it, and continue to receive withdrawals to that same address. Let's say you did this, and then you want to pay someone for something. Maybe we enjoy a dinner out together, I pick up the tab, and you send me sats to pay for your portion. If I look in any block explorer, I can see the address you paid me from, every withdrawal that you ever made from that exchange, and your current bitcoin balance! It gets worse...if you keep using that one address, I can see all of your future transactions too. Using a different address each time (which your wallet will automatically give you every time you click "receive") will avoid doxxing yourself in this way.
Bitcoin privacy is a rabbit hole...if you don't feel like you have the need or desire to dig any deeper into it, an amazingly effective bang for your sat is to avoid address reuse. Some exchanges support lightning withdrawals, which avoid this, whereas others will require manually adding a new address for each withdrawal. Do it...take that extra minute and give them a fresh address for each withdrawal. Your future self will thank you.
Hope to see you on Saturday!
Keep stacking sats, and keep stacking skills.
