But What if the scenario is Bitcoin designed to control people economically where few people know how to control it and the system lets people benefit from it with false indications on price (Demand and supply), It will be Easily to control people when all people in the world will be involved in Bitcoin
What are your Arguments?
Do you even know what the word "control" implies?
Take Bitcoin source code and read it. There is no possible way someone could change the rules on the fly on a whim, exactly what governments and financial institutions controlling fiat do.
False indications? Where? The current price is the result of the market forces, freely expressed with buy and sell. There is no entity behind doing nothing beyond what any other actor in the market can.
When everyone in the world is involved in Bitcoin, control over them over. Right now people are chained to the whims of a few politicians that can destroy their fiat's purchasing power overnight (I know well, because i'm living it).
No one can come tomorrow and decree that Bitcoin is suddenly valued at half (ie. increase the number of coins to 42 million). Such a change simply cannot occur without the vast majority of holders, miners nodes agreeing, and they have the economic incentive to NOT do that.
The more people move into Bitcoin, the less they will be controlled.
