Bitcoin really went up sharply and if you look at the price chart, you can see that it did not just grow and gradually become more expensive, but quickly skipped a few hundred dollars in a few minutes, so I believe that it can be a gamble on the part of people with large capital. Such sharp jumps could provoke the entrance to the exchange of a large amount of fiat money.
Recently, a well-known investor shared his thoughts on the future price of bitcoin. There is information that George Soros plans to invest large amounts of money in bitcoin in order to raise its price to 100 thousand dollars. Despite the fact that Soros called bitcoin a bubble, now people from his environment are investing in bitcoin and he is looking towards investing in bitcoin. Today's rise in prices for cryptocurrency may be triggered by an infusion of money from Soros investment funds.
