If we look at the chart of Bitcoin, we can also say that it will rise something more. It's just that right now there's lack of demand so it might be possible to have a temporary downtrend before it goes up again and makes another ATH. It is highly possible that this will happen this month or next month because afaik in January 20, trump will officially called as the President of the United States.
I hope that the "temporary downtrend" that you're saying is the one that happened a few hours ago when the market dumped really hard YET AGAIN, and Bitcoin from around $101,000 is now trading at around $96,500.
I hope that those traders out there didn't get liquidated at all. I'm not, so I'm safe, and based on one article, around $480 Million worth of money got liquidated in just a few hours. Welcome to the crazy world of crypto.

Anyway, if there's a volume, and a new money coming in after the inauguration of Trump then we might see an increase. Right now, the best thing is to accumulate Bitcoin at current price again and sell at near $100,000.
