When someone wonders how long to hodl bitcoin. It is because people follow a purpose and already feel tired.
If you need to sell some bitcoin, sell it.
It happened to me once, and it was for a good cause.
If you feel tired to hold, it means you have no good trust in your investment.
Why do you feel tired? You must buy crypto coins in hurry, then you set a target without good analysis. So, finally, you sold your coins because you give up to see the current market trend. Is it true?

You must get a big lesson after selling it carelessly. In the future, you need to do the deepest analysis before buying and selling a coin. Don't regret it after buying or after selling a crypto coin.
