I've been in BTC trading for two years. Never has anything been wrong with btc proper, it is always with centralized businesses around it, with the exception of the double spend fork of the blockchain during that one version upgrade early on, which was a valuable lesson for future upgrades like the recent 0.9 transition, which went smoothly.
And no, central banks are awful. That is one of the myriad reasons distributed compute power is what makes bitcoin strong. And ironically, central banks are autocratic and blockchains are democratic, while the systems that consistently produce the former are purported republics, and blockchains just come from no ideology or power structure, I guess anarchy.
> My prediction is that at the end there will be an epiphany that our real world currency system is constructed the way it is for a reason. It may not be perfect, it certainly has some major flaws but at the end of the day it's still better than the alternatives.
The current system is giving a monopoly on printing money without any backing store of value besides the confidence in the printer to a select few easily exploitable and corruptible appointed heads of central banks with no mechanism for the fair distribution of new funds. These banks then operate through violence to guarantee peoples assets to falsely make the currency look more secure than it is, by threatening you if you don't pay the taxes to recoup the losses of risk in storing your money with someone else. Is it an arms throw from the worst possible system, which would be the absence of any confidence at all, and it is only with systemic manipulation such a system still works at all. That, and the US dollar is the compulsory international currency for oil, which everyone craves like a cocaine addict without a fix.
