...wouldn't it be wise for MEGA-chinese miner or mega-bitcion-holders to exchange bitcoin with themselves
just to control/manipulate/stabalize THE VALUE of bitcoin?
Value of bitcoin is not based on "transferring" it around or back and forth.
The value is based on what people are willing to pay on the exchanges or through in-person trades.
That value is based on the need or desire to own bitcoin at that moment.
If the bitcoin price is "stable" it is because people are buying the available coins at a steady constant rate.
If they buy less, the price would go down, since now too many coins are in supply.
If they buy more, the price would go up, since now too many coins are in demand.
That might sound dumb, but if i was mining 25% of all bitcoin(like some chinese miner),
wouldn't be wise to use my bitcoin to create false transactions just to keep the price up or stable or what ever benefits me most?
As I stated above, the price is based on what is actually being bought and sold in the exchanges,
not what transactions are moving through the bitcoin network. Transaction numbers should not effect bitcoin price.
If a miner was placing their coins on the exchanges, and were buying and selling them over and over,
it would be likely over time that they would be doing this at a loss to themselves.
So in order for them to stabilize the "value", over time they would be losing money, even without fees.
