The Buying process of Bitcoins will have to be made much more simpler than it is at present. All indications point that the process will get more streamlined, so buying bitcoins will be an easy task. In most countries (US included), companies that trade Bitcoins onto the local currency would be regulated. More exchange companies will mushroom. 
I live in a third world country and buying bitcoins here isn't hard at all. Like, not at all. You can buy bitcoins in convenience stores. If you have 7-11 in your country, chances are they also have it there. You can use the machine to buy bitcoins and then that's it. Your problem is already solved. It's as if you just bought bitcoin from a store. No hassle at all and the process time takes only about 15 minutes. I'm pretty sure the future of bitcoin is really bright especially with that big price for each coin. People will notice bitcoin and when people start using bitcoin, the price of bitcoin will become more higher and bitcoin can be the next gold or even to be the most popular online currency for online transaction.
I agree with you . There are now many people who prefer to use Bitcoin as a means of payment because it is easier in life. I think in the future Bitcoin can replace cash and banks will have to use BitcoinBitcoin's population is increasing but not in the pace that it will replace cash. I don't think bitcoin will ever replace cash at all. A lot of people knows about bitcoin but only few of us are using it. Only few of us are embracing the idea of it and that will continue to be the case unless big companies and influential people start promoting it.
