We might need another couple of weeks before BTC if going to go higher. The big influx of people over November and December has temporarily dried up and we need time before people get use to the idea on BTC being in the 15K range before more money will flow in. This market is at a ATH, and the new money folks needs time before they see this range as being safe.
As usual, when BTC idles, ALTS will spike and that will happen as expected, so make sure you in your favorite ALT.
