We can invest bitcoin i think we can change the dream into reality very easily, we just need to buy bitcoin and then to hold it for so time tell the price of bitcoin increase to a good level and then we can sell it for securing a good profit.
To make your dream comes true, Bitcoin should become a centralized currency at all the places. I think most of people will agree with this and expect this to happen soon. If bitcoin become centralized, We can start businesses which is related to bitcoins. I am sure, we people in the forum will get profited if it becomes centralized money.
