Ah, I've been looking at the 15-minute interval chart. I think this may be a false crossover, unless the volume starts increasing. There also seems to be little support above $6.20.
I'm wary of looking at smaller timeframes in the BTC market. My main issue is volume / the spread. Much of the trading / charting that happens on the lower timeframes in BTC is really just noise and difficult to follow. Also, if you take a trade, the spread is so large that your position may never make money, even if you were right as to the trend direction for the next few hours.
