So, government will choose to ban non corporating DEXs than banning their allies CEXs.
The government does not need to ban Cex for decentralized exchanges to get more popular. With the knowledge that;
• Centralized exchanges are regulatory arms of the government,
• You do not own they keys and they are not your coins,
• Your coins can be hacked,
• Your private information can be stolen, etc...
Crypto users who are privacy inclined should opt for decentralized options.
