This is a really important area of resistance for BTC. The .50 fib is typically a best to overcome (though I don't doubt Bitcoins ability to smash through resistance). Consolidation needs to come at some points with profit taking. I think it's now.
With everything up (stocks, commodities, crypto), people may be derisking their portfolios very broadly and I'd expect crypto to feel that first with its outrageous volatility compared with the other asset classes.
Watch carefully, if this level does break, we'll be going up to the 0.618 (13467).
