When a person like Elon Musk tweeted and showed support for Bitcoin and claimed himself as the supporter of Bitcoin, it has put a positive impact on the market i the last two days which isn't surprise at all from the perspective of the present situation. Here Elon Musk may have a financial intention but already showed a positive impact.
If a single tweet from a personality like Elon Musk can cause a 10% spike in the Bitcoin exchange rates, then we should also remember that the opposite case can be true as well. Tomorrow some of the other multi-billionaires (such as Zuckerberg or Gates) can tweet that the government should destroy the cryptocurrency ecosystem and the markets can crash by 10% or more than that in a matter of hours. In the end, the truth is that Bitcoin remains a highly volatile asset which can go up or down by a large amount as a result of a single tweet.
