As I have read more about bitcoin. I think it is the number 2 that stands in all. It is one of the main reason for creating it. For better transaction and the cheapest way it could be.
and the possibility to never more use banks and be your own bank, i hope that this is going to be possible at some point in the future
It is already. You are your own bank. You can save money in it at the same time invested. Banks use your saved money to invest it also but the difference is they only give you a small percentage of it and it takes a long time for you to feel that profit. I would be picking bitcoin instead even if it is risky.
Saving your money in bank just like you're giving loans for them and it's different if you borrowing some money from bank the interest will be higher comparing with the interest you can get it for saving your money in them.
