It's been a while since the digital currency posted that value. The last time Bitcoin had a price above USD 9,000 occurred in May 2018, or more than a year ago.
Investigating, the presence of Facebook's digital currency has contributed to controlling the value of Bitcoin. Some investors say the social networking plan is encouraging people to buy Bitcoin. This shows optimism for the increasingly widespread application of cryptocurrency in the mainstream financial system.
The price movement is indeed very positive. Bitcoin is worth $9k, and there does not seem to be a reason for this to be the end of the upward trend. I honestly did not notice the $9k achievement, because Bitcoin has been worth almost that for some time now. At the same time, I don't think it has much to do with the Facebook coin. It's just that the positive trend kind of feeds itself. People now see that the market is clearly recovering, so they feel like now is a safe time to invest. This leads to even more investments as the price is growing and people don't want to be left out.
