The .618 fib is a level I am watch closely, you will see it has retraced to this level a number of times already during this rally. Bitcoin loves the .618 level! It then climbed back up, trading in the $6.5-6.8 range for 4 days before breaking down again and it's once again looking to the .618 level. I expect we may see a possible rally up to 6.2k, once the .618 is breached there will likely be an aggressive move down to the .50
