I first heard about Bitcoin around 2016 but then I had no idea what Bitcoin was. Someone online was saying to work on it because I don't know anything about it. Then I heard about Bitcoin again in 2022 when the price of Bitcoin was 21000 dollars. I did a little research on Bitcoin and saw that it was good. From whom I heard, I said to a brother, brother, let's invest. Buy a bitcoin and keep it.Fifty percent and I invested fifty percent but that brother did not agree then. Day by day the price of Bitcoin was increasing and the price was going up and down around 25, 30, 31 thousand dollars. Still I told my brother to invest but he did not agree. That price eventually reached 74 thousand dollars. I regretted very much why I didn't take a risk. If you want to do something, you have to take a risk, nothing happens without a risk.
