"Selling your art as an NFT is easy, simply Sign up, mint your art and wait for your collectors"...if only it was that easy.
I got into NFT space quite late, when it got famous for crazy sales and when almost everyone had known about it.. my grandmother probably had minted her art before me...I was that late. But then, the whole crypto movement is still quite early if we're to look at things from a global point of view.
So far, I've realised making sales as an artist goes beyond your talent to create art. Of course, the ability to create art is the primary skill needed for every NFT artist, communication skills, engagement, consistency, patience and dedication to one's craft are also quite important in when trying to sell you works as NFTs.
Some may begin making sales in just hours of minting their works while for some, if may take several months till the finally make a sale. Sometimes, people get lucky with making sales, but most times, sales come from several actions either already carried out before minting the works as NFTs or after.
Collectors also love to patronise an artist whose works appear to be valuable or rare. A 1/1 piece of art would most likely sell faster than a 1/20 piece. A reputation for creating duplications of art isn't very attractive and people tend to patronise those kinda arts and their creators much. Minting the exact same piece of art on another NFT platform is also a bad move. It reduces the value of the art and the artist. It kinda brings a curse to the artist and its really not a good idea.
Finally, Twitter is currently the meeting ground for collectors and artists. Your chances of making sales go higher if you're very active on Twitter. There are loads of NFTs spaces where artists get to interact, share their ideas and experiences while collectors lurk around to see which artists they would support next. It's crazy how people would make sales and some folks would think they just got lucky, well like I said, it could be luck, but luck is quite rare in the NFT space when trying to sell your art.
