I would suggest that in a market this thin TA should be considered for entertainment value only.
There's a dozen or so folks pushing this market around at will, and perhaps less.
I think TA still works as reliably as ever even with just a few large participants. Which is to say, only somewhat reliably.
In fact, if I had listened more to my TA instead of being super long term bullish on bitshares and not ever wanting to sell, I wouldve made more shares by trading.
If that was the bottom, we wont be able to be sure until much higher. But so far so good.
