I don't think that humans will ever be totally free because there will always be someone who wants "more freedom", primarily financial freedom, but power as well.
And they won't hold down of getting their higher freedom by lowering down or destroying someone else's freedom.
Same thing goes with banks. Their owners are super greedy.
Few days ago I went to a bank to see how much money I will get in interest if I put in $1million for a year...the answer was $4k. I will win more than that on sports betting if I bet that Liverpool will beat Red Star in football.

But if you try to take a loan for a $1million, you'll have to return much more than $4k.

Currently, I don't think cryptocurrency will make a real difference. After all, currency is currency. Although in cryptocurrency world we don't have banks/middle person to take a large cut on every transaction, which is good.

But even if we all adopt BitCoins or any other cryptocurrency, it would be a matter of time when the banks are going to shift to this new currency and start benefiting on it.
Even now we have marketplaces who take good piece of the action for cryptocurrency trading.

PS: I like the way you think, and general idea that you go for. With that in mind, are you open for some business proposals?
