to me if the bitfinex isssue was not happen now we will be trading bitcoin above 800USD. some people think that there is no special effect of bitfinex on bitocin but i will like to say that there is a great effect of bitfinex on the price of bitcoin.
The price was due for a serious correction as the price was bought up to levels that were purely the result of the hype and speculation around the block halving. With or without the hack of Bitfinex, trading above $600 is a very reasonable price if you ask me.
