My Love, My Bitcoin: Part II

Atta girl, Lucy!
Atta girl, Lucy.

I met my friend Mark for lunch today at the Walnut Room. We sat near the windows and looked out at the gorgeous Chicago spring day.

“I bought flowers for my mom online for Mother’s Day,” said Mark. “At the checkout, there was an option to pay with bitcoin.” Mark is extremely skeptical about pretty much everything, so he was grumpy: it’s hard to be wary of Bitcoin when it helps you buy flowers for Mom.

“That’s great!” I said, clapping. “I bought a mattress on with bitcoin. Did you read PaperGirl yesterday? It was all about bit –”

“Yeah, yeah, I read it,” Mark said. “That’s why I brought it up. I have questions. How do you buy them?”

I welcomed the interrogation. It was with some trepidation I dove into all this yesterday; talking to Mark might help me iron out the second half of my bitcoin treatise.

“You can go to, set up an account, and buy bitcoin,” I said, “Or you can buy bitcoin in person, from a trader. I went on and found a trader with a great customer rating and met him and bought bitcoin from him. It was easy. It was fun.” Mark knows that that trader was Yuri. So romantic, right?? I know.

“And you use real money to buy them,” Mark said, eyeing me. The waiter came and we both ordered the tortilla soup.

“Yes,” I said. “And they’re not actual coins, you realize. Each bitcoin is a line of code. And you put them –”

“Where do you put them?”

“In a bitcoin wallet, poodle. Just like you put cash or cards in a physical wallet, you put bitcoin in a digital wallet. Each bitcoin has its own serial number. Those numbers live in your phone or your computer. Remember, dollars have serial numbers too — and your credit card is a string of numbers — a lot of how bitcoin works we already use everyday.”

Mark shook his head. “What keeps someone from making up fake numbers? Making a fake bitcoin would be way easier than making a fake dollar bill, right? No paper. And is there a finite number of these things? Who invented it, anyway? And who’s profiting?!” Mark slurped his soup and then — with his mouth extremely full — he managed to say, “You’re never gonna be able to explain all this.”

I told him I’d try. And I’d keep it short, too.

In 2008, a programmer — possibly a group of programmers — known as Satoshi Nakamoto, wrote a brilliant piece of code and put it out on the Internet for free. Even the most dour of bitcoin critics agree: Nakamoto’s digital currency model was (is) genius. This is because his bitcoin model, among its other elegant features, got rid of two huge problems with buying goods and services online: 1) no longer did every single online transaction have to go through a bank or credit card company, with all their fees, security breaches, and data gathering; and b) he solved the problem of double-spending.

The first problem is easy to get your mind around, even if you don’t agree it’s a problem. Now, to that second thing. If you don’t have a bank or credit card company to vouch for you, to say, “Yeah, you really bought that llama — it shows it right here on your statement,” how can you prove you did? Equally bad — just as Mark worried — if someone, like a bank, isn’t monitoring the system, who’s to stop some guy from making all kinds of fake bitcoin and buying zillions of dollars worth of stuff (e.g., llamas) with fake money?

Nakamoto designed bitcoin so that the community of bitcoin users verify the transactions. Instead of a bank making one central ledger of what’s circulating, the bitcoin users do it, verifying all of the transactions — yep, every one of them — at the same time. There are a finite number of bitcoins in existence (21 million) and they all have a unique serial number or code. If someone tries to use a fake bitcoin, the transaction is caught as it tries to get through the system and it’s rejected. So there is regulation: it’s just in the hands of the people using the currency, not A Big Bank, not MasterCard or Visa. (We used to get along without those things, you know.) How all the verifications happen is rather complicated and computer-y and I am willing and able (more or less) to explain it. My fear is that I have asked much of you, gentle reader, and you have been most faithful; perhaps it’s wise to discuss that last bit (!) of the bitcoin system another day.

Two last things, and then let’s finish with the love story:

First, Bitcoin has a PR problem because in the beginning, the anonymity of the currency appealed to people buying nefarious things online. I hardly need to point out that as I type, lots of people are buying nefarious things, online and otherwise, with U.S. dollars, too. But this early sketchiness (and a trading company, Mt. Gox, that was doing bad business) dealt a harsh blow to bitcoin and it’s gonna be recovering from that for awhile. A few shady apples hurt the bunch, but as Bitcoin grows, matures, goes through a modicum of regulation, and problem-solves, these early specks will flick out. (Also: the “crypto” in “cryptocurrency” refers to the encrypted codes within the system, but people see “crypto” and register “cryptic” as in “confusing.” It’s not a perfect word, “cryptocurrency.”)

Lastly: Bitcoin is new. Really new. Anyone reading this is way ahead of most of the general public — and good for you! Curiosity and inquiry = great! More and more merchants are accepting the cryptocurrency for payment (e.g., Amazon, Gyft, Overstock, etc.) but until you can pay your energy bill online with it, bitcoin has a ways to go. It takes a village, but remember: the Internet itself was new not so long ago, and people were skeptical and cynical about it, too. Look where we are now.

One of the reasons I care so much for Yuri is because he wants to build the village. He believes in the ability of bitcoin to make the world a better place, so he works tirelessly for his company, a bitcoin trading firm in NYC. He is a miner. He goes out of his way to patronize businesses that accept bitcoin. He gets involved in the growing, global community and recently gave a lecture at his alma mater about his work. A person with a passion is a beautiful thing to behold. And to, you know, hold.

“I still don’t know,” Mark said, pushing his empty soup bowl away. “But I think it’s cool you tackled the topic. Good job.”

I thanked him, and paid the check. With my credit card.

    So, since the exchange rate is something like $438/bitcoin, how do purchases work? If I’m spending $5, am I debited 1 bitcoin or 0.01142 bitcoin? Likewise, if I want to buy bitcoin do I have to buy one bitcoin or can I buy, say $50 worth to try it out? Also, is bitcoin pluralised with an s, or is it like the plural of moose?

    Thank you for writing this. Our accounts have been hacked six times in the last four years. We’re getting tired of having to change our bank cards. We’ve gone mostly cash and checks, but you can’t use cash at Amazon or Knit Picks, you know? I’d like the bitcoin alternative, but without someone who knows about it to ask questions of I was uncomfortable.

      A single bitcoin can be subdivided to 8 decimal places. So, the smallest unit of a bitcoin you can own (nicknamed a “satoshi”) is 0.00000001. Most exchanges enforce some kind of minimum transaction amount, say $1 or $5 worth. So yes, you can buy small amounts and not necessarily a whole bitcoin. In your example, $50 could get you about .115 BTC today.

      General consensus on nomenclature: when talking about the protocol, or the technology, you capitalize – Bitcoin. When talking about the currency as a unit, you use lowercase ‘bitcoin’. If talking about multiple units of currency, such as 10 bitcoins, you can make it plural, lowercase.

      And boo, it’s LocalBitcoin[s].com – plural. brought us together. It IS romantic 😛

    Thanks for the great articles! I think I am beginning to understand Bitcoin. I do have a question about the exchange rate. Say I want to buy Make + Love Quilts on Amazon. It is currently listed as $17.34, and eligible for Prime shipping (yay!). How does that translate into bitcoins?

      DeAnn, you are great. Yuri did something cool: you can order my book with bitcoin, now! Woah! Now, you’ll need to get some, first. Go to and start that. But when you’re ready, Try this: Pay With Bitcoin

      And thank you for reading and being intellectually courageous!

    It never ceases to amaze me how much I learn from reading your podcast! It’s sneaky too, because I come here for your stories and leave knowing more about things that apparently I need to know about, but never knew about. 😉

    I heard about Bitcoin on the Freakonomics podcast a couple weeks ago and they mentioned that the process of mining uses enormous amounts of energy. They quoted that as many as 3 million homes could be powered with the electricity used to mine bitcoins. Does the Bitcoin community and specifically the trading organizations have a plan to prevent this new currency from becoming a huge issue environmentally, especially as it grows? It seems like it solves so many social/political/economic issues dealing with currency that it would be unfortunate if there was an equally problematic trade-off for the environment.

      Jenelle, you are very smart and observant.

      Yes, mining does use a lot of energy right now — it’s kind of like early air conditioners were probably pretty inefficient at keeping houses cool, but as we get smarter and make better mousetraps, that’s a lot less the case (e.g., EnergyStar certifications, LEED certs., etc.)

      What you asked, about the Bitcoin community, well, that proves your smarts and that you’re gonna be just fine in the world. Because that’s exactly what is happening AND what needs to happen more and more: Bitcoin community members being more active, working together, problem solving together, all that. Because yeah, if Bitcoin is great for money but bad for the land, what in the world good is it?

      In short: yes, Bitcoin mining uses a lot of energy and that is lame, but it’s changing. Does it make you feel better to know neither Yuri or I have a television or a car between us? That’s not me being cheeky! I mean it: we kind of balance out our energy usage. Thanks for reading PaperGirl and for engaging in the world. xo, Mary

    Thanks Mary (Papergirl). I followed your blog for quilting and now am learning about bitcoins. Please continue the lesson, as I’m sure that’s the way we’re are going. Maybe have Yuri chime in and give us a weekly lesson on how to invest in the bitcoin community without getting scammed?? Thanks again for sharing your knowledge!!
