Summary:
- The UK's tax authority, HMRC, has sent out over 65,000 letters to people suspected of not paying taxes on their cryptocurrency investments.
- This is more than double the number of letters sent out last year, indicating that the government is cracking down on crypto tax evasion.
- The letters warn recipients that they may owe back taxes and penalties, and encourage them to come forward and declare their crypto holdings to avoid further action.
