If you don't know how to analyze

In the immediate case, as soon as Bitcoin goes down, we enter any currency that is going down with it, given that most currencies go down with Bitcoin, but we make sure of two things

1- The ruling on the currency in Islamic law, is it forbidden or permissible

2- What is the market value of the currency (do your research about it)

And thus we sell on the rise, meaning if Bitcoin rises by a candle, your profit is big, don't be surprised, you will take a strong profit, and in the same way, you pray for me, and if it goes down, you don't have to worry because its destiny is to go up

(Patience is the key to relief)
