Bitcoin does not crash. It has a volatility rate of 4% which is better than any other currency or asset so people can stop saying that it crashes as it always comes back. Zoom out on your price timelines people.
I would like to know how did you calculated that bitcoin has 4% volatility rate, or where you read about it. That's putting the bitcoin volatility very precisely!
I Agree that btc is comparatively less volatile than other cryptocurrencies.
