before we decide to invest in bitcoin then we should know about bitcoin and look for reliable information about bitcoin, so we will know and be ready with all the risks that might occur including when the market goes down
Personal experience is much more important.
When I first heard about bitcoin 6-7 years ago, I didn't take it seriously.
When I finally got involved and got my first bitcoins, instead of saving them, I wasted them on nonsense.
When the price of bitcoin grew very much, I realized my mistake and started over.
After that, the price of bitcoin repeatedly had a big rise and a big drop, but I never repeated my mistake.
I know from experience that when the market goes down, it's the best time to buy more bitcoin and to hold.
After every drop in value, there is always growth and so it has been for 10 years
