Researchers have come to a shocking conclusion that at least half of the rise in the prices of major cryptocurrencies and bitcoin may be due to a concentrated campaign of price manipulation.
Bitcoin exchanges are working in an unregulated space. Whales with massive amounts of money are taking profit where they can.
So while it indeed makes sense that the price has been manipulated up to 20k $, it also has been manipulated down to 6k $.
And this manpulation game did not stop yet. And it probably will take quite some time until the manipulation has been decreased to an 'acceptable' level.
Currently the two
best options are to either (1) hold long-term and don't care about short-term swings or (2) play the game and try to get the most out of it.
