Pushes often occur around important events in projects' roadmaps.
For the specific case of Solaris project, I guess this in the launch day of txbit.io exchange.
No one know when it will be released after several delays from Solaris core team.
It seems that they should test it carefully to make sure no serious technical issues happen after launch.
Another push in price is coming as more people are becoming aware of the Solaris project. My fear is the ability to maintain the price when the rise comes. So, Solaris needs more Market makers with very fat pocket of cash and btc.
