Actually it is not the market cap that decreased, it is the market value. Investing during this season is actually an advantage. Transactions are high which makes the demand and value of Bitcoin low. But the thing that matter is its market value will again, increase. And those who will invest now will surely earn hugebprofit when that time come and that is expected early first week of 2018.

The price is more or less the same now than what it was at the beginning of December... down from $18 000+

This the absolutely the best time to buy more bitcoins, because the price is relatively low now. After every correction thus far,

we saw a break out past the previous record high price. If you buy during the dip <which is now> then you would make some

very good profit at the peak. 

Buy low, sell high. It’s that time of the year. People made some profit taking to have money to spend on this holiday. Invest in bitcoins right now, while no one is looking.

Christmas is almost over and indeed we can see that the price is rising again. Probably the last days to buy low, although I may be wrong and this situation will stay couple of weeks longer. You are right on the price being very seductive right now. After seeing $20k recently $14k looks like a dream.
