# Buying a Passage
**Purchasing a Passage involves the following:**
* Select an underlying asset from the drop-down menu (e.g. BTC)
* Based on the estimate range, decide if you believe the asset will stay in long enough to at least breakeven (1 day) or breakout faster than 1 day
* The payoff range diagrams provided show the range of price as well as the linear payoff depending on the side of the trade the user takes
* If you'd like to place a custom order, you can adjust using the ⚙️icon.
\
Example: “Stay in” position with $100 investment - starts at $0 and accumulates over time until the first price breakout. Maximum duration (2 days within the range) is 100% profit ($200).
\
Example: “Breakout” position with $100 investment - starts at $200 (100% profit) and clicks down over time until the first breakout
* Specify the amount you would like to buy. This is denominated in the native coin of the chain (e.g. ETH for Arbitrum, BNB for Binance, etc.)
* Claims are rewarded in the same asset used to invest
### Select Slippage
\
You will also have the choice of applying "slippage" or a 0.1% amount that will be subtracted from the order placed. E.g., an order at ± 1.2% range w/slippage of 0.1% would match with an order at ±1.1%. Slippage is designed to improve order matching P2P. \

### Trade with existing balance
If you have funds on the smart contract that have not been withdrawn, Passage will ask you if you would like to use them toward a new trade. You can toggle this on or off.
