The crisis was largely due in part to deregulation and private companies getting kick backs for their ratings. Crypto currency is mostly unregulated and rated on a private market. Also, there is a small elite group of people who own most of the crypto currency, which very quickly and easily could result in market manipulation at the expense of small holders. While your anger is understandable and banks are indeed criminal, cryptocoins are just as susceptible to criminal behavior as any other market place and even more so do to the lack of regulation. And I’d just like to note that major banks like Goldman are saying that btc is bullshit while quietly buying a massive stake in it. So, the fact is, the banks will get involved if it’s worth money and they will manipulate the market, so we will be right back where we started.
