Everyone knows cryptocurrency market is highly volatile and risky.
And most of the people do emotional trading.
They sell when it is crashing. And suffer from the loss. They panic and sell in the loss.
What is the point in selling at low?
One must wait for the market to turn green and bullish.
The way to stop the panic is to not engage in panic-inducing activities such as day trading.
It is like the old joke; a man goes to the doctor and says my arm hurts when I put it overhead.
The doctor says don’t put your arm overhead
If you are in need of urgent money than selling is OKAY but for profit, HODL is the best.
In my own opinion, for you to stop panicing in selling bitcoin, you must have a calm mind. Focus yourself that you need to earn a high profit but it needs a long time. You must have patience in waiting for the price to rise up. Then you must know some news about the price daily for you to know if the price is rising or falling.
