When countries block crypto exchanges, where does the money go?
Correlates real-time internet censorship data from Voidly with on-chain blockchain fund flows from Nansen to reveal how smart money adapts when authoritarian governments block crypto exchanges.
Built for the Nansen CLI Challenge #NansenCLI
Interactive CLI for real-time crypto censorship intelligence:
# Is Binance accessible in Turkey right now?
python3 censorship_alpha.py --check binance.com --country Turkey
# Compare censorship across countries
python3 censorship_alpha.py --compare China,Iran,Turkey
# Real-time smart money signal for BNB chain
python3 censorship_alpha.py --signal bnb
# Quick ranking of all 15 countries
python3 censorship_alpha.py --rank
# Full 10-section HTML report (17 Nansen CLI calls)
python3 censorship_alpha.py --report --png --json# Prerequisites: Python 3.9+, Node.js 18+

When authoritarian countries block crypto exchanges:
- BNB Chain DEX volume is 31x higher than ETH DEX among smart money — consistent with Binance being the most-blocked exchange globally
- BNB 30d net flow: -$751K while Base (Coinbase ecosystem) is +$18K — capital migrating from censored to uncensored ecosystems
- Exchange censorship predicts broader internet censorship — countries that block exchanges almost always block social media, news, and messaging too
- Privacy tokens are a leading indicator — micro-cap privacy/VPN tokens see volume spikes when exchange blocks increase
