I hope your predictions will be right, however I somehow believe tech analysis is rather good to interpret the past (so after the change really happened) :P and the lines seem more and art then sci to me (not your lines - tech analysis lines in general).
PS did you ever check if tech analysis make sense at all this way: take random piece of BTC prices from the past, draw your lines (seeing only that historical part), and then uncover what was there later and if those lines match? And experiment like this? :) I wonder what would be a % of correct predictions...
