I am a graphic designer and I love to draw digital art, can I use just my random drawings as NFT and sell them on opensea or wherever? Basically, what should I do to make my digital art an NFT?
Well, the first think you should know is that NFTs are nothing more than links on a blockchain. A string of text that links to where the image is stored. That's it. There's no magic there or anything you need to do to your image. You just need to host it somewhere and put a link to it on the blockchain, which is the NFT. A "token" that links to an image.
Go to Opensea and create one, so you understand the process. Yes you can use your own graphics.
As a beginner, better use a cheap blockchain, g.e. Polygon.
Learn how to handle sending and receiving NFTs.
Buying an selling or even making money with that is a different story...
Well, I don't think that using OpenSea to create an NFT will teach you anything except how to use OpenSea's NFT maker. In reality, most people could learn how to issue their own NFTs in a day watching some YouTube videos. It's isn't a difficult process and doing it yourself without using an intermediary like OpenSea might actually teach you something. Once you've learned what an NFT is, you can start to understand what's possible. Functionality will be the key moving forward. People have realized the "artwork" NFT scam was nothing more than creative fundraising.
