pob should have its value which individuals can't manipulate

Maybe that's some people's wish, but it is impossible as real money is used to buy and sell the tokens not imaginary numbers. An interesting thing to consider is the actual price of the token. If someone buys POB for 10 dollars today that is not the actual price you will be able to sell your POB for. The next day it can go down to ten cents. It just means a certain number of tokens were sold at that price. It doesn't reflect the entire value of POB but the value that one person felt POB had for that moment. That pump though would have an influence on the price for a short time. The value of a token is in how it it is used and by how many people and how often it is used. There is also value in the plans and ideas of a token. So POBs value is very much dependent on its users.
