I saw many small startups growing based on crypto themes. Several groups create crypto merchandise to sell on platforms like Instagram profiles and websites.
Some examples are
https://www.etsy.com/market/crypto_merchandise
https://cryptogoodies.shop/
https://cryptowardrobe.com/

Now I'm thinking that I'm gonna make these kinds of merchandise and sell these platforms. But don't know about the market potential. Is the people of crypto ecosystem are really interest to buy crypto merchandise stuff?
