Bitcoin have a limited supply of 21 million coins.
The only way the terrorist organization Federal Reserve can manipulate Bitcoin is if they print out trillions of their scam U.S. Dollars and buy up more than 60% of all the Bitcoin supply.
That will put Bitcoin in a giant bubble, new investors will buy into Bitcoin thinking it will continue to rise in value.
After a short period, that terrorist organization Federal Reserve dump massive amount of the Bitcoin they own to cause the price to drop rapidly.
Most new buyers will panic and sell to take a big loss.
