If it looks like a duck, walks like a duck and quacks like a duck, it's probably an NFT (sorry, duck). Emojis which indicate profit, money etc are equivalent to words, IMHO.
As a child I collected, 'collectable' cards, which came with chewing or bubble gum. Each pack cost a few pennies. Previously there were cigarette cards of famous cricketers (in the UK), or baseball players (in the USA). but the selling company never expected to make a profit from them, it was more of a marketing enticement (so that children would pester their parents to buy said consumable so that they they could complete a 'set').
I must say that I have no NFTs, no cryptocurrency investments, and am deeply suspicious fo them (I have a Ph.D. in pure mathematics, published a paper on cryptography and worked for over 20 years in information security). If you can't scratch glass with it, it ain't hard currency.*
