Yes, you should believe in BTC, although I generally see it as a payment system and not as an investment.
of course all the people should believe in bitcoins and i think that everyone will believe in bitcoins as the price of the bitcoin is going to rise at an incredibly rapid pace in my opinion
That's the problem, most people see bitcoin as an investment. We should see and use of bitcoin as what it really is, a currency. Most people here just want bitcoin because they know they can profit, they don't want to circulate the coin like using it in buying services, etc. They just want to hold, making the circulate of the coin unusable. It is like holding some barrel of oil to help the price increase, you're like holding the supply and the supply cut you will be happy that the price will increase.
