I think the Trump NFTs were my first time hearing of perpetual trade royalties. Most of the NFTs I own are tied to games though... maybe it's more common in the art space and chains I don't frequent.

I was into BTC before anyone really had a good place even check the value and would waste them on side projects and also gamble them away randomly like they were Chuck E Cheese tickets. It does not keep me up at night, in fact everyone constantly checking the price of crypto is almost the antithesis to Crypto in my opinion. The investing mindset is kind of nauseating, you can't talk about any project without price being brought up.
