the unlicensed exchangers are a plague and they must be removed.
I'd rather not have my documents and bank accounts at risk for hacking/identity theft. And I'd rather not have the IRS in my business. Why does that make these exchanges a "plague?" They are only such if you believe that the US government should be in control of the movement of money, generally. Why?
they are a plague because they made a bad image to any e-currency. people lost funds.
if you don't like fiat, close all your bank account and live without them
a regulated market(only with licensed exchangers) is the way; otherwise, BTC will collapse.
Yes, because the entire concept of Bitcoin received popularity due to its regulated, centralized, government controlled, big banker correlations...
