Introduction
In September 2024, a Binance user publicly claimed their account was restricted after declaring cryptocurrency as their sole income source. The exchange requested documented proof of annual earnings and tax compliance, sparking widespread debate about cryptocurrency's role in modern finance. This incident highlights the growing tension between decentralized asset ecosystems and traditional financial regulations.
