I saw my friend displaying photos of profits and green candles on social media. It attracted me a lot, so it was originally an advantage. And that's money.  It was the first time I heard of Bitcoin. So I've known Bitcoin for almost 8 years and have gone through two halvings. So I feel very lucky to know Bitcoin because with this I can help improve my economy. To be precise, I got to know Bitcoin in 2015, it was after I finished my final college assignment. Although I am familiar with trading, it turns out that Bitcoin is very broad. There are many factors that influence it.
