Half a year ago, I invested in bitcoin, and then I chose to sell all of my bitcoins for $19,000, and I got a lot of money. Then the price of bitcoin fell. When his price hit $11, 000, I chose to buy it, and then the price of bitcoin continued to fall, and now it's only about $7,100. But I still believe in bitcoin, and I'm not worried that it will cause a lot of damage to me, because I use the money that i earn invested in the bitcoin, and I believe it will return to the highest point.
