Frankly, because of the illiquidity of many cryptocurrencies, i.e., they can easily be broken by one "entity"/trader, one shouldn't put too much weight on trendlines in my opinion.
All the more reason for me to go somewhere that matches my trading style better. Any market maker worth his salt should be defending that trend line.
Whoever you are, and I know you're in here, you SUCK at being a whale. Go beach yourself.
