Selling your crypto right now is a serious mistake not to be made, especially for long-term investors.
You should sell when the market gives a sell signal (which is not the case currently) and not when it starts to go down.
The current decline of the market in general and Bitcoin in particular is a way of telling buyers to pay attention to price movements because a reversal can occur. 😉
Avoid making decisions out of fear; you'll lose the money anyway 🤷♂️.
