For those diving into the world of BTC NFTs, you'll find it's growing fast.&#x20;

Just like in Ethereum, you can sweep a bunch of NFTs at the floor price all at once on marketplaces like OKX Web3 or MagicEden. But, there's a twist with BTC NFTs – there's no way yet to set up a bid that automatically buys NFTs when their prices drop to where you want them. That's where BTCBot's Auto Buy steps in, letting you pick a price and how many NFTs you want, and then it does the buying for you when the price is right.

You can follow these steps to bid or sweep Ordinal NFTs in BTCBot.&#x20;

* **Choose an NFT collection**: Switch the NFT collection you want to buy using the left and right buttons. You can also click on the NFT collection name to open the collection list and make a quick pick.
* **Choose the Buy Mode**: Opt for Sweep Mode to purchase NFTs at the current market price, or select Bid Mode to acquire NFTs at or below your specified price.
* **Setting the Limit Price**: If you're bidding, you can set the price based on a percentage drop from the current floor price (0% means the current floor price), or you can set the price directly based on how much each NFT is worth.
* **Setting the NFT Amount**: Decide how many NFTs you want to buy.
* **Setting the Expiration**: Set the expiration period for limit buy orders. The order will be automatically canceled after the expiration period has elapsed. The default is 7 days.
* **Submit the Order**: Check over how many NFTs you're getting and the price, then submit the order. Then, you can view the list of active bid and sweep orders in the interface.
