How hard would it be for Central Banks to buy 90+% of all Bitcoin now&future.
If they did this they could effectively crush the price on the exchanges, making bitcoin unprofitable to mine and secure… After a few up and down swings they would effectively corner the market financially and once enough of you's get burned, you wouldn't dare put another dollar into bitcoin..
They could effectively take control of the price, crush the network similar to oil manipulation, and if so desired then, control the rate of creation of bitcoins IE they could always sell and buy, with the narrative, it is our intention to destroy bitcoin, the network behind it if you touch bitcoin, you will lose…
Considering the lag required to get Fiat into bitcoin via Centralized exchanges they could easily manipulate the price lower by having the largest fiat balance in the market and also the largest bitcoin balance, and they could easily act as buyer and seller manipulating the price lower..
I doubt the mass market would adopt the p2p transactions or local bitcoins or anything not heavily regulated and protect leaving a void on the buy side..
Perhaps defeating the FED over time might work, but it could take 20-30-50-100+ years before they lose control and the reality seem, if they want to have possession of 99.98% of bitcoins they could. And the price being $1
It is also unlikely to think the mass market will adopt a different alt coin for the fed to wage its financial war again and cause a huge score of more losses as the fed accumulates the alt coin and then forces the price back to zero-ish.
90% of the coins are not even in existence but buying 90% of the existing coins may be theorically possible but 90% of the bitcoins would need to be sell to them.
