No one is controlling the price of crypto currencies but people's minds can be manipulated by spreading positive and negative news about crypto currencies.So the price movement will also be according to their rumors.But banks don't have that much impact on the bitcoin price in my opinion.But if media spreads that news too much then it will have a big impact.
The fluctuations in Crypto are unlikely to be controlled, but there are still a lot of people who are fortunate enough to succeed in the Bitcoin market. The top and the top are Bitcoin, the king of virtual coins. Bitcoin is widely believed to be influenced by a lot of places, but Bitcoin's actual development or agility is not related to anything.
