Frequently Asked Questions

When did China ban cryptocurrency and why?

China's crypto crackdown occurred in phases: ICO bans in 2017, exchange shutdowns in 2017-2018, and a comprehensive mining and trading ban in September 2021. The bans were driven by concerns over capital flight, financial stability, energy consumption, and the government's push for a digital yuan (DCEP).

What is Europe's MiCA regulation?

Markets in Crypto-Assets (MiCA) is the EU's comprehensive regulatory framework for crypto assets, adopted in 2023 and fully effective from December 2024. It establishes licensing requirements for crypto service providers, stablecoin rules, and consumer protection measures across all 27 EU member states.

What major enforcement actions has the SEC taken against crypto companies?

Notable SEC enforcement includes the 2020 lawsuit against Ripple Labs over XRP sales, the 2023 lawsuits against Binance and Coinbase for operating unregistered exchanges, and numerous actions against ICO issuers. The SEC's approach of 'regulation by enforcement' has been highly controversial in the industry.

How did the Bitcoin ETF approval change the regulatory landscape?

The January 2024 spot Bitcoin ETF approvals legitimized crypto as an investable asset class within traditional finance. It signaled a shift from pure enforcement to accommodation, established a regulated on-ramp for institutional investors, and set precedent for future crypto-based financial products.
