The fact that there is a bullish setting in the Altcoin (Bullish Downward Symmetrical Triangles, Cup & Handle, Jaws of Wealth) patterns, Bitcoin is not expected to top for a while now. I can't see BTC doing it's big picture correction while the Altcoins are so bullish. So, as said in recent updates, I believe the top will be signaled by the Altcoins once they execute their bullish patterns. When? Not sure yet.
