# How to place a buy order

{% hint style="info" %}
*You don't have to match the exact quantities within the orderbook, but you do have the match atleast the minimum order size.* 

***Minimum order Sizes per Type:***\
The First Transaction, Palindrome, Uncommon: *<mark style="color:red;">**1**</mark>* \
Nakamoto, Block 78: *<mark style="color:red;">**1,000**</mark>* \

1. Choose the quantity you want to **BUY**
2. Choose the price at which you want to sell. We've chosen a price of 65 [Satoshi's ](/saturn-v1/faqs/what-are-satoshis-rare-sats-and-rings.md)per Nakamoto, because this is the lowest sell order on the orderbook (check rightside).&#x20;
3. Here you see the total value of your order. In this case we are buying a 1000 Nakamoto's at a price of 65 Satoshi's, so the total order size is 65.000 (1000 x 65). Right above this input field, you can see the balance, or total amount of Satoshi's (BTC) in your wallet.
4. Under 4, you can see the Sell-order in the orderbook, that we are trying to fill with our buy-order.&#x20;
5. Click on "Swap".&#x20;
6. In the following window, you have to choose your Fee rate. If the Bitcoin network is busy, it is recommended to choose Medium, or Fast.

7. Click "BUY". Your order is now entered into the Orderbook. If a sell-order at your buy-price, is present in the orderbook (like in our example) it gets filled immediately. If there is no sell-order at your buy-price, it get's added to the buy-side (bottom) of the orderbook.
8. Congratulations! You just bought some Satoshi's.
