This lesson answers

  • Why is Bitcoin going up or down today?
  • Why is Bitcoin so volatile?
  • Who sets the price of Bitcoin?
  • Has Bitcoin crashed before?
  • Why is the price different on different apps?
  • Is it too late to buy bitcoin?
  • Will bitcoin go back up after a crash?
  • How do interest rates affect bitcoin?

There is no official bitcoin price. It is simply the price of the latest trades between buyers and sellers on exchanges around the world, which never close. New coins arrive on a fixed schedule, so when demand changes, the price is the only thing that can move.

What usually moves it

  • News and rules. A country banning or approving something, a big exchange failing, or a new kind of fund being allowed.
  • Big buyers and sellers. Funds, companies and long-time holders moving large amounts.
  • Borrowed money. Many traders bet with borrowed funds. When the price moves against them, platforms sell for them automatically, and those forced sales push the price further.
  • The wider economy. Interest rates and stock markets: when investors get cautious about risk in general, bitcoin often falls with everything else.

Headlines that explain a day's move are usually written afterwards. Most days several of these happen at once.

Why it moves more than most things

A share in a company has profits to anchor its price; bitcoin has none, so the price rests entirely on what people expect. It trades every hour of every day, the market is smaller than the big stock and bond markets, and borrowing to trade is common. Moves of 5% in a day are common, and bigger ones come with little warning.

Big falls before

PeakLowFall
June 2011, about $30November 2011, about $2about 93%
December 2013, about $1,150January 2015, about $170about 85%
December 2017, about $19,500December 2018, about $3,200about 84%
November 2021, about $68,000November 2022, about $15,500about 77%

After each of these, the price later passed its old peak. That is history, not a promise: nothing guarantees it will happen again, and nobody, including us, knows where the price will go next.

"Is it too late?"

People have asked this at nearly every price in bitcoin's history. Nobody knows the answer, including us. What the history does show is that timing mattered a great deal: people who bought near a peak sometimes waited years just to get back to what they paid, and some sold at a loss before then.

Check yourself

Practice, not a test. Think of your answer first, then reveal it.

1Why can't more bitcoin be made when demand rises?Reveal

The supply follows a fixed schedule, so when more people want to buy, only the price can adjust.

2What is a liquidation, and why does it make moves bigger?Reveal

When someone has borrowed to bet on the price and it moves against them, the platform sells for them automatically. Those forced sales push the price further the same way.

3Does a past recovery mean the price will recover after the next fall?Reveal

No. The history shows what happened, not what will happen.
