if the financial companies want to control the price, they must prepare big money to buy bitcoin but the truth, they cannot control it. we know that bitcoin cannot control by anyone and the price will follow with supply and demand in the market. and now, we see the price is going from yesterday and we have a few days more to see the price is rise again or fall deeper.
Bitcoin can not be controlled that is true, but other ways of manipulation exist such as a 51% attack. This threat is very real. Once an organization, or a couple of organizations join together and control 51% of the network, they are able to determine where the mining rewards go to.
This can be detrimental to the system as a lot of people have invested money in building mining rigs to mine btc, and such a 51% attack would mean that they lose their investment. Of course people can switch to mining other crypto coins so all is not lost. But for the btc system as a whole, the value would substantially decrease if a 51% attack happens.
Luckily some second-gen crypto coins are working on this 51% attack problematic.
Other ways big corporations can control the market is by releasing fake news to hype or drop the price. It is thought that the banks in China have done this , by releasing "btc banned in china" articles, they saw that this manipulated the price. Every time such an article would surface, the price would drop and they buy more btc.
The same happened with the CEO of JP Morgan. One day he says that btc is a fraud and he advises investing against it. As a reaction the price of btc drops significantly. You can guess three times who bought the most btc that day. If tyour guess was : JP Morgan, JP Morgan and JP Morgan, your guess was right!
The blockchain technology is here to stay and big institutions fear it. That's why they will do anything to control this section of the financial market, of which they have absolutely no control (ironical isn't it). We will see a lot more fake news articles and crypto bans in the following months.
Just stay vigilant on the information that's being spread and do your own proper research. That way you can ride on the manipulations the big corporations create for you rather than being the one who is on the losing end of these market manipulations.
