I've gotten a few of these types of scam attempts recently.

The first was someone on Instagram who wanted to buy one of my works to use as a reference photo for an NFT for $1,000. I was extremely skeptical since they could purchase a stock photo extended license for far less, but since she had actually singled out the work she wanted, and sent me a couple of messages, I agreed to take a look at the proposed contract, in the hope that I was wrong. As soon as I read the "contract," I knew my misgivings had been correct. It purported to make me responsible for upfront costs, which they'd "cover" by sending me more than the $1,000 price for use of the image - a big red flag - your bank can "cash" a check for you based on your own balance covering it, only to discover several days later that it has actually bounced, meanwhile the contract required me to be responsible for various costs on a very tight timeline - before the time it would take to discover a check or credit card payment was actually no good. I politely declined her offer.

I've gotten DMs on twitter too asking if my work is for sale - when it's clear from any link that it is, followed by "I'd love to buy it as an NFT" - without specifying a specific work - another big red flag. I just respond politely that my work is not available as an NFT. I probably shouldn't waste my time responding at all but since I've had individuals, publishers and galleries contact me out of the blue who were legitimately interested in showing, licensing or buying my work, on the off chance that my cynicism has made me assume a legitimate inquirer is a scammer, I always respond politely even when I'm saying "no."

Since NFTs require you to spend money up front, they seem like the perfect way for a scammer to get your money. And if they offer to pay for the NFT costs up front and then send you more than needed, requiring you to repay the difference, or pay others, well, that's just a reworking of an old photo scam from the early 2000's. 

@ZeroTalent  Thanks for bringing this to people's attention - that some here don't believe you is a testament to how scammers stroke photographer's egos and why conmen have been succeeding for eons. It's easy for me to spot a bogus "contract" but I practiced law in NYC for over a decade. It's also easy to understand how much we want an offer to buy our work to be legit - I actually agreed to look at the "contract" even though I really knew deep down that it would be bogus. Human nature. Now I just politely decline so as not to waste my time.

I'd worry too if they are sending you to their own bitcoin site, that they can get more than whatever costs you're paying upfront, since this might give them private banking info? It could wipe you out, and my understanding is that none of this stuff is traceable.

Yet another day in the never ending story of:
