From the Peanut Gallery

This post is in response to an interview on the One Hundred Trillion podcast, a debate between Ryan (the host) and Paul Puey (CEO of Edge Wallet). They discussed and debated a range of topics related to Bitcoin's value proposition and historical/current narratives around it. The following are some thoughts I have on certain points I think are worth commenting on. First, I'd like to explain the lens with which I observe and think about these tools. My Values For a system like Bitcoin, I value...

Bisq: Fiat Methods

This is part of a series of posts on Bisq, the peer-to-peer Bitcoin trading platform. This series will serve as a primer to a Meetup presentation planned for February 2024. Background One of the good things about Bisq being an open protocol is that all the trade info is transparent. Anyone can download the entire history of trades and use that info to see where the liquidity is, increasing your chances of a successful trade. But that's only one of the things to consider when chosing a paymen...

Bisq: There is no Surveillance Discount

This is part of a series of posts on Bisq, the peer-to-peer Bitcoin trading platform. This series will serve as a primer to a Meetup presentation planned for February 2024. The biggest misconception about using Bisq (and other no-KYC platforms) I hear is that it's "too expensive." This is likely due to looking at the "Buy" tab and seeing most offers with at least a 5% spread: I don't blame people for coming to this conclusion. If you're used to using a large exchange, you don't usually see...

Don't Use Ledger Live

Everything you do in ledger live is being tracked, the code is embedded in "critical logic," and most of it goes to third parties, not Ledger. This software is required to initialize and update Ledger hardware wallets. You don't need to use it for sending and receiving Bitcoin, you can use Sparrow for that. Still, you'll eventually have to update the firmware, so you're better off getting a different device. This company has graduated from insecurely storing your personal data to giving away yo...

Bitcoin Robberies in Sweden

I dont see many cited sources in English for this, but it seems that the country of Sweden believes it's a good idea to expose people's personal income and tax info for anyone to see. There has been a surge of Bitcoin holders being attacked and robbed. The root cause of these attacks, according to Wall, is Sweden's Offentlighetsprincipen laws, which allow public access to personal data such as residential addresses and tax records. He argued that criminals are misusing these laws and social me...

Third Party Doctrine

The third-party doctrine is a United States legal doctrine that holds that people who voluntarily give information to third parties—such as banks, phone companies, internet service providers (ISPs), and e-mail servers—have "no reasonable expectation of privacy" in that information. A lack of privacy protection allows the United States government to obtain information from third parties without a legal warrant and without otherwise complying with the Fourth Amendment prohibition against search a...

16 Year Party

A friend came to me and said "what if we celebrated the halving like a global holiday?" I said "yeah totally!" Well that dude came back to me a while later with a plan that I initially thought was crazy, then went ALL IN. Background If you don't know what the halving is, here are the nuts and bolts: Bitcoin is hard money due to it's supply cap and planned issuance That issuance is currently 6.25 BTC (currently worth $218k) every 10 minutes This is reduced 50% every 210,000 blocks (~ 4 years) ...

Personal Finance Tidbits

I was in a conversation in the August meetup with a few attendees talking about the tax implications of living off of bitcoin and discussed some lesser-known facts: If you are married and living off of bitcoin alone, you can sell more than $116,950 worth of bitcoin in 2023 and pay $0 in federal capital gains taxes. This is due to the $27,700 standard deduction and $89,250 bracket with 0% rate. It's about half for single filers. "More than" is because you are taxed on earnings, not what you s...
