> **Short answer:** Use a paper exchange that runs on live prices, so the prices and the mechanics are real and only the money is pretend. On [Rizon](https://rizon.markets/?ref=learn-how-to-practice-bitcoin-up-or-down-for-free) you open the page and you're trading: $1,000 of practice money, no signup, Bitcoin contracts over 15 seconds, 1 minute or 5 minutes, each paying a fixed 2×. Practice four things: judging how far a strike is for the time left, keeping one size, trading release minutes, and keeping a log. Then work out what fees will do to your numbers before you trade real money anywhere.

Polymarket and Kalshi trade real money, and their up/down markets charge takers a fee (1.75¢ a share at 50¢ on Polymarket). Practicing there costs money on every trade. Practicing on paper costs nothing, as long as the paper market is real enough to learn from.

## What a useful practice market needs

- **Live prices.** Simulated prices teach you a simulator. Rizon's Bitcoin price comes from Coinbase, with Kraken as a backup. If the live feeds stop, the market pauses: no new orders, and contracts that expire meanwhile are refunded.
- **Real mechanics.** An order book, other accounts on the other side (often Rizon's market-making bot), positions that settle on the actual price at expiry.
- **A score that's public.** Rizon's leaderboard ranks every account that has traded by realised PnL, people and bots alike, so practice has a scoreboard.
- **Short horizons.** You learn from outcomes, and a 15-second or 1-minute contract gives you dozens in a session.

## Getting started on Rizon

| Step | How |
|---|---|
| Open the site | rizon.markets: an account with $1,000 of practice money is made for you, no email needed |
| Pick a horizon | The bracket under the chart, or `←` `→`: 15 s, 1 m, 5 m |
| Pick a side | Hover the blue line (higher) or the orange line (lower) on the chart's right edge, or press `↑` or `↓` |
| Confirm | Enter, or the chip's Confirm button |
| Watch it | Your position is a green line at its strike and expiry second; the price runs toward it, and through it |
| Refill | Once your balance is under $10, "Refill paper balance" in your account puts it back to $1,000 |

Every contract starts when you trade and runs its full length, so there's no window to catch and no price to beat set before you arrived. You pay your size; if Bitcoin finishes on your side of the strike you get twice it back. Exactly at the strike is a push and you get your size back.

Rizon's Bitcoin horizons are 15 seconds, 1 minute and 5 minutes; there's no 15-minute contract. If 15-minute windows are what you'll trade elsewhere, practice on the 5-minute contract: the skills below are the same, and you get three times as many outcomes.

## Five drills

1. **Distance before direction.** Before each trade, say out loud how far the strike is from the price, and compare it with a typical move for the horizon (table below). A strike $20 away is beyond the median 1-minute move and inside the median 5-minute one. Getting the direction right doesn't help if the strike was too far away for the time left.
2. **Fifty trades, one size.** Pick a size and don't change it for 50 trades. Log each: horizon, side, distance to strike, result. After 50, check your win rate against 50%, the break-even on a 2× payout with no fees.
3. **The release minute.** Trade the minute after a scheduled release, such as CPI at 8:30 a.m. New York time. The first minute after CPI has typically been about ten times an ordinary minute (the median) ([the data](https://rizon.markets/learn/cpi-fomc-bitcoin-first-minute)). Practice how quickly strikes move, and how wide the book gets.
4. **The thin lead.** Hold a 15-second contract into its last seconds when the price is within a few dollars of your strike, and watch how often it changes sides. In fixed 5-minute windows, a lead under $10 thirty seconds out was overturned 31% of the time ([the data](https://rizon.markets/learn/how-often-does-bitcoin-reverse-in-the-last-30-seconds)).
5. **The quiet hours.** Trade the same horizon at 14:00 UTC and at 21:00 UTC. In the 30 days to 26 October 2026, the median 1-minute move was $29.85 at the first and $10.20 at the second. Same contract, a third of the range.

## The numbers to keep in your head

From every second of 27 September to 26 October 2026, with Bitcoin near $83,000 ([full data](https://rizon.markets/learn/how-much-does-bitcoin-move-in-15-seconds-1-minute-5-minutes)):

| Horizon (s) | Median move ($) | 90th percentile move ($) | Price unchanged (%) |
|---|---|---|---|
| 15 | 5.07 | 26.01 | 17.13 |
| 60 | 15.37 | 54.58 | 5.18 |
| 300 | 36.55 | 123.47 | 0.52 |

If you trade from code, `GET /api/v1/markets` returns each market's `sigma`, its realised one-sigma move over the horizon from recent ticks, so you can check distance in today's terms ([API docs](https://rizon.markets/docs)).

## Mistakes that cost the most

- **Doubling after a loss.** On a 2× payout, doubling the size after each loss means the sixth trade after five straight losses is 32 times the first. Five losses in a row at even chances happens about 3% of the time: rare per streak, routine over a few hundred trades.
- **Treating paper as free.** If you'd never trade $500 of real money on one 15-second contract, don't do it on paper. Practice the size you'll use.
- **Trading the window, not the price.** In fixed windows, late in the window the side that's ahead is already expensive: a random arrival in our data found it worth a median 74¢ ([the data](https://rizon.markets/learn/fixed-windows-vs-horizon-contracts)). Being right about direction isn't enough if you paid for it.
- **Forgetting the feed.** Each venue settles on its own source (Chainlink's BTC/USD average on Polymarket, CF Benchmarks' index on Kalshi, Coinbase on Rizon). In close calls, a few dollars between feeds decides the result.
- **Counting wins, not PnL.** A 60% win rate at 70¢ prices loses money. Track profit and loss, not hit rate.

## Before you trade real money

Fees move the break-even. On a cents market, buying a share at price p wins 1 − p and costs p plus the fee. With Polymarket's crypto taker fee (shares × 0.07 × p × (1 − p), [fees](https://docs.polymarket.com/trading/fees)), the win rate you need is:

| Price paid (¢) | Break-even win rate with no fee (%) | Break-even win rate with the taker fee (%) |
|---|---|---|
| 50 | 50.00 | 51.75 |
| 60 | 60.00 | 61.68 |
| 70 | 70.00 | 71.47 |
| 80 | 80.00 | 81.12 |
| 90 | 90.00 | 90.63 |

Makers (resting limit orders) pay no fee on Polymarket. Kalshi's taker fee uses the same formula, rounded up ([fee schedule](https://kalshi.com/docs/kalshi-fee-schedule.pdf)). If your paper win rate at 50¢-equivalent prices is 51%, it doesn't survive a 1.75¢ taker fee.

## FAQ

### Can I practice Bitcoin up/down trading without money?

Yes. Rizon is a paper exchange on live Bitcoin prices: you start with $1,000 of practice money, without signing up, and trade 15-second, 1-minute and 5-minute contracts.

### Is paper trading realistic?

On a live-price exchange, the market is real: real prices, a real order book, real accounts on the other side of your trades, often Rizon's market-making bot. What's missing is the pressure of real money, which is why it helps to practice at the size you'd really use.

### What win rate do I need on a 2× payout?

50%, ignoring pushes, on Rizon, which charges no fees. On a cents market, the break-even is the price you paid plus the fee: 51.75% for a 50¢ share with Polymarket's crypto taker fee.

### Does Rizon have 15-minute Bitcoin contracts?

No. Its Bitcoin horizons are 15 seconds, 1 minute and 5 minutes, and each starts when you trade. For 15-minute windows elsewhere, the 5-minute contract is the closest practice.

### What should I practice first?

Distance: how far the strike is from the price, against a typical move for the horizon. It decides more short-horizon trades than direction does.
