I think that the bottom in December 2015 was the end of a C wave in a major A-B-C correction that started back in 2007. If that is the case then either the bullish trend is going to continue or the correction can become more complex. Whichever way it takes, I think there is more upside, as this is either a corrective A wave or a wave 1. The question I can't answer is in the two alternative counts on the chart and that is if the price will continue straight up or it is due a imminent correction. My inclination is to go with the pink count.
