What you will be able to do

By the end of Chapter 15

01Lay out your own plan in four steps and ten sessions, with dates, at a pace and an amount that fit your life.
02Choose what to read, watch and listen to next without drowning in it, and tell a teacher from a salesman.
03Answer the question “so, what do you think of Bitcoin?” in under two minutes, without preaching.
Try it

Do it on your phone or laptop

  1. Write the plan. Fifteen minutes, on paper or your phone. Go to yourbitcoinbasics.com/ch15 for a printable version and the milestone page.
  2. Write today’s date and the date you expect to finish the tenth session.
  3. Under Learn, write which chapters you will reread, and one thing from the lists above you will read, watch, or listen to all the way through. Put a week next to each.
  4. Under Buy small, write an amount you could lose without noticing, or write “not yet,” which is a complete answer. Put a date next to it that falls after you have reread Chapters 10 and 11.
  5. Under Secure, write where the words will live and who, if anyone, will know. Put a date next to it.
  6. Under Share, write the name of one meetup, in person or online, and the date you will sit in the back of it. Then write one sentence you would say if someone asked what you think. Use the script if you need it.
  7. Find your Chapter 2 note and staple it to this page.
  8. After the tenth session, come back, print the milestone page, sign it, and put it with the seed phrase. You will find both again some year when you need them.
  9. Photograph your signed plan. This is the page the whole book was building toward.

Check yourself

Did it stick?

Rate yourself: yes, mostly, or not yet. Not yet means reread that section. It does not mean you failed.

  • I can name the four steps of the plan, in order, and say why buying comes after the safety chapters.
  • I can write my own plan with dates, including “not yet” as an answer.
  • I can apply the four tests that separate a teacher from a salesman to a new Bitcoin source.
  • I can explain, with one example, why showing changes more behavior than telling.
  • I can answer “what do you think of Bitcoin?” in under two minutes without predicting a price or telling anyone what to buy.

Scenario

At a family dinner, your brother-in-law says, “You’ve gone quiet about the Bitcoin thing. Did you lose it all?” Your niece, who is 19, is listening. What do you say?

Say your answer out loud first. Then open the model response.

Show the model response

Not at all. I stopped talking about the price and started learning. I bought a small amount I could afford to lose, I hold the keys myself, and I wrote down where the backup is and who to call. The price goes up and down, and I do not check it every day. Then, to your niece: if you are curious, start with what it is, not what it costs. I am happy to show you.

Takeaways

The Part, in five sentences

The closing in five sentences
  1. Holding money that keeps its rules can teach patience, and patience grows from trust.
  2. Bitcoin can fix some things about money. It cannot fix scams, wages, or rent.
  3. Learn, buy small, secure, share, in that order.
  4. Be the peer, not the preacher: answer when asked, and let people see your plan.
  5. Things change after a book is printed, so check yourbitcoinbasics.com for what is new.

Test yourself on this Part with the short quiz.

A fair objection
“Isn’t ‘be the peer, not the preacher’ just a softer kind of recruiting? You are still trying to get people to buy.”
My answer

Partly, yes, and you should hold me to it. I do want more people to understand Bitcoin, and I have spent five years teaching it, so I am not neutral, and I have said so throughout.

Here is the difference. Recruiting has a target and a quota. The peer plan has neither. Its instruction to you is to do your own small thing well and answer questions when asked, and it counts as a success if your sister looks, understands, and decides no. That student’s sister could have done exactly that. Nothing in the script asks anyone to buy, and the fourth line tells them who to talk to instead of you. If a “peer” ever pushes an amount, a deadline, or a price, they have stopped being a peer, and you should apply the same rule to them that you apply to me: the pressure is the red flag.

What I will not pretend is that showing is neutral. It is not. Watching someone you trust do a thing and be fine is persuasive, and the research in this chapter says it is more persuasive than any argument. That is exactly why the rules in “What not to do” exist. The power of the peer effect is why you should use it carefully, and why this book puts the safety chapters before the buying chapter.

Don’t confuse
a plan vs a wishA plan is written, dated, and reviewed; a wish is “I’ll get to it.” This chapter is a plan.
learning vs buyingThe sessions are for learning first; buying comes after Chapters 10 and 11, or not at all.
