I think BTC has bottomed based on extreme similarities with the previous bottom on the weekly chart. NVT, RSI, 50, 100 and 200 MAs all coincide with the current bottom. Also, the channels forming support and resistance are near identical to the last bear market.
The only thing missing from the current bottom is the big volume spike which occurred when the price breached the 200 MA during the last bottom. This can be explained by the fact that we did not have a similar breach of the 200 MA this time around and also a lot of the volume is potentially occurring on the OTC markets and also spread across other exchanges both of which didn't quite exist to the extent as they do now during the previous bear market.
