I think every year is repeated. And at the end of 2018 with new volumes will jump even higher than in 2017.
Your mindset is wrong from the beginning. Every year is different, but why do you have to wait till the end of 2018? Why not trade at this very moment and take advantage of the situation? What if we ended the year on a bad note? The market is unpredictable and we can't control the price, but we can control and make good trades. There are no signs that we are out of the woods yet and the bullish market that we all have been waiting might not happen this year.
