I think its cause people believe an alt coin will dethrome
bitcoin since bitcoin has mining centralizatiom problems and no consensus on protocol changes esp the 20mb issue.
Bts offers more tps to fall inline with visa mastercard. They prob just pick the top 5 coins with dev teams and bought up.. will probably be back.. seems its a coordinatrd buying spree.
Funny you say that.. the talk in bitcoin is a believe that it will double next year when bitcoin halves in 2016.
The price of bitcoin has stabilized dramatically and so it is becoming far more tolerable to the risk adverse.
It could be a hedged bet like you said.
What if someone in some higher power position knows something is about to come down for crypto and decided to get in while everything is rather cheap? Why now of all times?
