This indicates that money is starting to shift from Bitcoin to altcoins.

Altcoins may really be waking up; before, they seemed to be playing dead, barely moving during dips and showing no strength during rallies. Now, there's finally a bit of a heartbeat—though they haven't jumped yet, at least they're no longer lying flat.

Money in the market is starting to take notice; the big brother (Bitcoin) is well-fed and slowly shifting his gaze towards the little brothers. Those altcoins that are low in price and haven't really risen much look cheap and have interesting stories, and funds could jump in at any moment to make a move.

Those shorting altcoins should also be cautious; the biggest fear right now is a sudden change in market momentum. While you're watching them look bearish, they could unexpectedly surge by 30% or 50%, and you won't have time to react before getting liquidated.

You think they’ve been lying around for too long, but they think you’re shorting too aggressively. Once they start to rally, they could sweep you right into the liquidation list.
