What wil happen to Bitcoin if we acquire the 21M BTC?

If the 21M btc mined already the value of bitcoin will rise because the investors and the holders will increase and the only source of bitcoin is only in trading. the demand will become higher but the supply will become lower.

Bitcoin's value is linked to scarcity and supply & demand. The rarer the commodity, the higher the value of that commodity. In theory the price will then go up as the scarcity increase, depending on the demand. The demand must also increase for the price to increase.

Compare it to Gold, to make it easier to understand, The more demand there is for Gold, the higher the price will be. We already know there are also a scarcity of Gold. ^smile^
