I think $800 is not a bigger amount and besides of that hack it will reach to $800 in the=is year, maybe in the end or a few months before from the end of the year.
Yeah, Bitfinex hacked and bitcoin price suddenly down, but if we are talking about only $800, so it is not big amount for bitcoin, also mostly chances are here that bitcoin might be come up, and 4 months are remaining for the end of the year. Price rise up and down it is a quality of cryptocurrency, and specially those people who are still using the bitcoins they will continue buying and selling the bitcoins. They never left the bitcoins only for hacking reason.
