We are only in the middle of the month so let's not judge that this month of December is a black month. Who knows in the coming days, that there are some good news out that will trigger the market to turn green because we know that this market always surprises us, so it would be better if we still holding some crypto to not get left behind if the situation change.
Basically, only a bit more than a week is left in this year. I really doubt that after Christmas, anyone would bother to announce something or do savage trades.
What we all expect - a new ATH as a minimum, or $100k for one Bitcoin as a maximum. I find it hard to believe that something might trigger such a growth. 15 days left till NY, even if the price increases for $1k everyday, new ATH wont be achieved. At least because the price would always pump down a bit.
