Most people are now busy preparing for Christmas. Buying gifts, attending parties, etc. I myself did a lot of profit taking to be able to celebrate the holidays in style. Would love to give bitcoins as a gift.
It's true that some people will sell bitcoins or at least some satoshies to have some extra money for the holidays. But I don't think that would be such big amount to influence the demand and supply ratio and the price in some significant way. So, I don't expect some huge price drop and disturbance on the market, usual volatility and nothing to panic for.
Regarding the gifts, some bitcoins as a gift would make me very happy too.
That's the theory, but the fact bitcoin price still increasing by the end if the year, despite the fact that many people sell bitcoin for Christmas party, buy gifts, foods, etc. What makes the price declining? Simply because the network can't afford current transactions, too much unconfirmed transactions and ridiculous high fee to be paid, the mempool just stuck at this point. And there are some options to invest or use it to move the funds without having a problem such as in bitcoin, there are bcash, eth, dash, and litecoin as better coins, just to allocate the funds before getting back to bitcoin again. Don't worry, it just the time matter until bitcoin rise again.
