According to Diar Research, ICO's cashed out 433,000 Ether ($ETH) in December, equivalent to $52.4 million. This is the largest withdrawal by month followed closely by November, which saw 290,000 Ether withdrawn. The analysis does not provide details of where the funds were moved to and while in some cases ETH was likely sold on an exchange in others it is possible that projects were simply reallocating funds between addresses.
