NEO/USD

Whats the reason for the recent spike all the way from $56 just on the 29th december to as high as $109.60 almost a 100 percent in one week.The price has tried hitting the $109 resistance twice , would be wary to buy there as it is becoming a stubborn resistance however another strong support forming around the $95 line and there is also a confirmed support line at $89 just below the 200EMA.
Will go long from $89-90 support line with a take profit around $109 or Hodl if there is a break out of this line and close at the resistance line calculated at $116,
