You can bid on specific NFTs or on entire collections.
Placing a “floor bid” on a collection will allow any owner of any NFT in the selected collection to accept it. If you bid on an individual item, only that NFT's owner can accept it.
By placing a floor bid, you might get any NFT from the collection, but the chance is greater that your bid will be accepted. By bidding on an individual item, only one person can accept your bid and you'll only get the item you chose.
How to Bid:
1. Go to the explore page and find the NFT or collection you'd like to bid on.
2a. To place a floor bid on a collection, navigate to the collection and click "Place floor bid". Reminder: This enables any owner of any NFT in the collection to accept your bid.
2b. To bid on an individual item, click on your favorite NFT and click on the three dots on the bottom right-hand side of the NFT. Then click "New bid."
3. Enter your desired bidding price and expiration date. Then, click on "Place bid."
4. Sign the transactions in your wallet.
5. Your bid offer has been placed. Now, just wait to see if it'll be accepted!
You can find the NFTs that you have bid on under your activity.
