We are not quite in the "need to use BTC" stage yet. At most, it's an alternative to what we are all accustomed to. But it's a good alternative that can as your own bank, in which you alone have control.
of course it is a really great thing to have control on your money in my opinion because banks take this chance from people and it is really bad thing to be honest most probably
i think that people should use more bitcoins because in my opinion the price of the bitcoin is going to increase a lot and make them a lot of money over time, thats the best currency
