For me, holidays didn't affect bitcoin value or market. In my opinion, it still depends on a user of bitcoins on how they will use it and how many time did they sell or buy it how many users are still using bitcoin until now. It always depends on us that the market will depend on.
Last year there was some fall in BTC prices before Christmas. This was because people were cashing out their BTC or taking out their profits, may be to enjoy their Christmas holidays.
