I'm wondering if it would be a good/bad idea to sell the shower gun cookie pic because I'm narcissistic and a total sellout.
Odds are you wouldn't be able to make much money from it. Unless you've got a large social media following or can get the thing to go viral, not too many people will be interested in it, so the odds of it going for a lot of money at an auction are pretty slim. Now, I know what you're thinking, "It doesn't really cost me anything to make it, so it'd be free money." And you'd be wrong. First of all, you have to get your NFT listed on one of the sales sites, that costs money. Then, when somebody buys your NFT, in order to complete the transaction and get your money, you have to pay what's known as a GAS fee. Think of it like the fee an ATM charges you to pull money out of it. The faster you want the transaction to process, the higher the GAS fee. The lowest GAS fees can take months to process, if they ever do, BTW. One of the podcasts I listen to has ~1 million followers, and one of the co-hosts is a photographer and he started selling NFTs of some of his photographs, but he eventually quit, because even though he was able to get hundreds of dollars for his NFTs, by the time he paid the listing fees and GAS fees, he lost money.
You might be able to sell the "original" file as an NFT. Maybe. But then again if you uploaded the original, proving you have the original could be hard to prove since it would identical to a copy of the original that can be found online. I think. I don't know. The NFT thing is still somewhat confusing to me.
Yeah. And while a lot of people here and there call it viral, it's more of a quasi meme. It's a legend at AR15.com, but not so much anywhere else. What about a T-shirt though?
It costs you nothing to have it for sale on a site like TeeSpring (or Spring as they seem to have rebranded themselves), you'll have to do most of the marketing yourself if you want to sell any. If you want to buy one, they'll sell it to you for a discounted price.
