I am saying that not literally destroy. I just want to say is to limit the number or the supply of btc to increase its price. Sorry for the term "destroy".
by actually limiting the supply, there is already a limit, as I stated before, a maximum of 21M of max supply but if you are talking about the distribution of bitcoins, it is also has been stated before that there is a halving year which it will decrease a block by 1/2 of the current value every 4 years
So you mean that every 4 years the value of btc will decreased. so that the supply will not affect the price of thr btc. And you also mean that is the enemy of the price of btc.?
no, every 4 years the number of bitcoins in 1 block will reduced by half the current amount, today 1 block = 25 bitcoins, in 2016, 1 block will be 12.5 bitcoins, this is about limiting the distribution of bitcoins
Supply will effect the price if only there is a real demand to it, because if there is no demand on it, it will be known as abundant supplies
i.e If you got 10 candies but you only need 1, then the rest 9 candies will be worthless as it has no value, and different cases is if you got 10 candies and you need 11 candies, the value of each candy will rise
If the each candies will rise the value if you need 11 but you have only 10 . How will effect the price?
then each candies will rise in value, because everyone will be pursuing this , the main reason of price increase is the buy power, if something is valuable enough , people might start buying it, if there is alot of buy power, the price will drive higher, remember, in every buy there is a sell, someone who bought lower will sell it higher
Do you think she/he will sell it? Whar happened if he/she eat it or use it? What will happened now? The price will be higher or lower?
in a trading, each buy is a sell, so each time anyone but a bitcoin. he / she will sell it for higher maybe not now, perhaps tomorrow or two days later, no one will be keeping it forever, or atleast use it, if he/she intended to use it, it will switch ownership, the new owner will sell it to another one, thus repeat the process
anyway this in only an analogy, the true system is that there are hundred thousand of bitcoins trades occuring each day, in short, if there is buy force the price could be drive higher
