Each of these categories and spaces can be explored, for example, if we go to CryptoPunks, we can see the entire NFT catalog that is there.
Clearly in these spaces you can appreciate the amount of NFTs available in the market, the people who are within it (the owners) and the commercial volume of the NFTs in the last 24 hours, which gives you an idea of the immense level of this market.

How to create your first NFT in OpenSea
Creating your first NFT in OpenSea is very easy. However, you must take into account some things:
- If you are converting a painting to an NFT, don't expect it to reach a high value. Most of the value of an NFT is linked to its originality. So the more original, rare and unique, the higher its value. Of course, this is only one factor, but it is the one that has the greatest impact. So please keep that in mind.
- Many people think that an NFT is automatically irreproducible. The truth is that anyone can make a copy of it and place it on the blockchain, but this would be easily recognizable. This is possible because the original NFT has a hash, a blockchain address and a smart contract that can NEVER be duplicated, so these elements would end up defining the difference between the original and the copy.
- It must be taken into account that if the NFT has a centralized point, its fall or alteration can lead to the loss of properties of said NFT. An example of this we could see when several NFTs were altered by an artist on OpenSea to prove it.
Now that you have this in mind, let's proceed to create our first NFT in OpenSea. The first step will be to go to the button «Create»Or«Create» within OpenSea to start with the generation of the NFT.
Now, the first thing we will do is have the NFT at hand, which in this example will be an image in JPG format. You will like to know that OpenSea allows you to use images (JPG, PNG, GIF, SVG), audio (WAV, OGG, MP3) or video (MP4, WEBM) so your creation opportunities are immense. The following is to indicate both the name of the NFT, an external link (to give more information) and a description of the NFT. You fill in each of these spaces with the data you want, and in the end you will get something like this:
Below you can select other options that you can add to your NFT, such as adding it to any collection you have or applying special properties to it. In addition, you can choose the network on which you will create the NFT, in this case, the Ethereum or Polygon network.
To finish you just have to click on the button "Create" and with that you will have your NFT completely created. Congratulations, you have created your first NFT within OpenSea! The result of the steps we have taken in this guide can be seen in this link.
How to sell the NFT that you have created?
Now, you have created your first NFT and you are wondering how can I sell it? Well, it's very easy. All you have to do is enter your NFT space and click the button "SELL".
Once this is done, you will see a new page where you can place the price of the NFT you want:
Along with other important data such as the duration of the sale period (6 months by default), you will see the OpenSea service fee (in this case 2,5%) and the network where the token is (in this case on Polygon) , after filling in all the data we have the possibility to list our NFT by clicking on "Complete Listing", with which the sale period of our NFT will begin.
After clicking, you must perform a series of actions that will allow you to list the token and finally you will be able to have your first NFT for sale within OpenSea.
