Product Description
The “Blockchain Currency 21M Tee” celebrates the foundation of the decentralized revolution. A clean, structured design pays homage to Bitcoin’s immutable 21 million supply—a symbol of scarcity, conviction, and trustless value.
The front layout layers collegiate-style typography with stacked phrases: BLOCKCHAIN Currency, BITCOIN, and 21M rendered in bold varsity lettering. Beneath it, No.1 acknowledges Bitcoin’s place as the original, undefeated digital asset.
Constructed from heavyweight 100% cotton for a substantial yet breathable feel, this tee combines classic streetwear structure with crypto-native minimalism. Designed for those who hold, build, and believe.
