Bitcoin Takeover Podcast Season 17

Bitcoin Takeover Podcast, S17 E14 with Kristian Csepcsar — Chief Meme Officer of Braiins & Author of The Ultimate Bitcoin Mining Guide

This one was recorded in person at the undisclosed Braiins office in Prague, the first of a whole series I filmed in their studio. Kristian Csepcsar runs marketing at Braiins (I introduced him as the Chief Meme Officer and he loved it), travels the world with a drone and a giant inflatable Bitcoin to document mining operations, and wrote The Ultimate Bitcoin Mining Guide, which you can download for free or listen to as an audiobook narrated by Guy Swann. He also handed me salami made out of whale, straight from Norway. I ate it anyway.

The main theme was a short history of Bitcoin mining, told by the people who lived most of it. Slush's pool started in late 2010 as the "Bitcoin.cz mining pool", mined its first block on December 16, 2010, and has mined 1.3 million BTC since, which makes Braiins a serious candidate for oldest Bitcoin company in existence. We went through Satoshi's email asking Laszlo to stop GPU mining, the arrival of ASICs, the Butterfly Labs tragedy, the 2011 Linode hack (3,000 BTC that Slush paid back from his own pocket, and which helped give birth to Trezor), and the industry-standard 2% pool fee that was picked more or less at random.

From a post-maximalist perspective, my favorite part was Kristian's rant about the centralization nobody talks about: Bitmain's closed-source firmware on roughly 80% of the world's machines, and Foreman's grip on mining management software, which is far stickier than any pool. We also covered Braiins Hashpower and solo mining as a lottery with better odds than Powerball, the depressing moment when solo mining Bitcoin Cash was briefly more profitable than Bitcoin, public miners pivoting to AI, Bitmain's playbook against challengers, and why Braiins stays KYC-free with Lightning payouts. I hope that you will find it useful!

Stats for nerds: Kristian's episode sits at 3,976 plays across audio, YouTube and X, and the X livestream replay carried most of that with 2,399 views. Turns out whale salami and pool fee archaeology make a decent combo.

Hows your Zcash "investment" doing? 

Remember that?

Pepperidge Farm remembers.

LOL.

LOL.

On what price point did he get in? ZCash has been surging more than any coin this year and last year, and I believe the surge started below $50.00?

LUCKY, but personally I could never HODL a coin such as this. It doesn't give the same feeling of safety that I get from Bitcoin.

I just looked at the chart for the first time in close to a year and I'm forced to eat a big pile of crow.

I just didn't care for it when he started shilling it at the local top with a bunch of other Twitter influencers. This was about a year ago.

Zcash is doing pretty good pricewise, but also development wise. Don’t stay zidelined, try a wallet sometime

Bitcoin Takeover Podcast, S17 E15 with Danny Plainview & Chad Master — OP_NET, Smart Contracts on Bitcoin L1 & the Great Stablecoin Unlock

Every cycle, Bitcoin gets a new protocol that half of Twitter loves to hate. This season it's OP_NET, which promises Ethereum-grade smart contracts directly on Bitcoin layer 1, with no bridges, no sidechains, no wrapped assets and no gas token. So I invited the two co-founders, Danny Plainview and Chad Master, to defend themselves. We recorded in the days around OP_NET's mainnet activation, and my cat showed up around the eight minute mark, presumably to audit the code.

The technical part was more interesting than the Twitter fights. They call it a consensus protocol rather than a metaprotocol: everything lives in the witness field of standard Bitcoin transactions (no OP_RETURN), contracts compile to WebAssembly and are written in TypeScript, and every node recomputes the exact same state from the blockchain alone. Danny used the Magic Eden shutdown as the cautionary tale for Ordinals and BRC-20, where you're basically hoping that everyone's indexers agree. The honest limitation: an OP_NET transaction is as fast as a Bitcoin transaction, because it is one.

I put on my toxic maximalist hat twice (Liquid USDT, then Tether over Lightning), and Danny had answers for both, plus what might be one of the most quotable lines in the history of this show: "ETH is a much better Bitcoin layer 2 than any existing Bitcoin layer 2." We also covered OP-20S stablecoins with an oracle-set peg, trustless BTC loans without selling, the BIP 110 crowd's miner-incentive and spam objections, why the priority fee makes MEV hard, and the security budget, which is where we found real common ground. There was also a Zcash giveaway from Cake Wallet. I hope that you will find it useful!

Stats for nerds: this one has been played 4,976 times across audio, YouTube and X, and 3,622 of those came from the X livestream replay. Fitting, since half of Twitter loves to hate OP_NET.

Bitcoin Takeover Podcast, S17 E16 with Summer Meng — CEO of Bitmars, the "ASIC Queen" of Bitmain Miner Distribution

If you want the latest Bitmain hardware in Europe or North America, the machine that everyone else lists as out of stock, Summer Meng is the person you contact. She is the CEO of Bitmars, the largest distributor of Bitmain ASIC miners on two continents. We recorded in person at the Braiins office in Prague, and she ended the episode with one Zcash from Cake Wallet in her brand new wallet (after we found her a phone, since she had left hers behind so it wouldn't interrupt the recording).

Her path into mining was an accident: COVID stranded her in China, a friend suggested a job interview, and she never left. What I found most interesting is that the 2021 China ban is exactly what turned Bitmars into an international business, since the machines suddenly had to go somewhere. She also told me about a second crackdown almost nobody covered, in Xinjiang last December, and the beautifully absurd legal situation where making and selling miners in China is legal, but mining with them is not.

We also talked about how a distributor can undercut the manufacturer, orders of 10,000 ASICs, public miners pivoting to AI, Bitmain's roughly 80% market share (and why Intel and Samsung walked away), impersonation scams, and her Chinese translation of the Braiins mining guide. My favorite part was heat reuse: Nordic projects, ASICs heating pools and drying salami, and small home units that are, in her words, wife approved. Every radiator in your house is more wasteful than a Bitcoin miner. I hope that you will find it useful!

Stats for nerds: 2,349 plays across audio, YouTube and X so far, with the X livestream on top at 1,128. Audio is right behind at 1,011, so people clearly like their ASIC talk in the background, like a miner humming in the living room.
