Although Buffett says Bitcoin is mouse poison squared, it seems that his thinking has many lessons for holders in the crypto space:

1. Emotional Management: If you cannot control your emotions, you cannot control your money.

2. Long-termism: Our holding period is forever.

3. Margin of Safety: The first rule of investing is to not lose money.

4. Contrarian Thinking: Be greedy when the market is fearful, and be fearful when it is greedy.

5. Circle of Competence: Only invest in industries or companies that you understand.

6. Economic Moat: Choose companies with sustainable competitive advantages.

7. Compound Interest: Enjoy the exponential growth that time brings.
