Apart from what Patatas mentioned, I would recommend you to hire a designer to design some shirts for you, if you want to become "The #1 Crypto Apparel Site". I have seen these designs before. Plus consider reducing your prices.
This keychain which you are selling for $9 is being sold for $1.7
on Aliexpress. Also, I am not sure if these designs are your own. Plus you are using Shopify's theme. Consider spending some money on the website Design too.
Sorry for being blunt, but you need to do a lot of things to claim "The #1 Crypto Apparel Site" title. You are not there yet. Anyway Goodluck with your project!
