In my opinion, for whatever it matters, in a year from now the price of BTC will be way above 10k. So from my perspective it doesn't really matter if it goes up or down a couple dozens or even hundreds $.

Whether it will go up or down  tonight... No idea. My crystal ball is out of order atm. Just buy some. If it goes lower buy some more. In other words, just cost average and don't invest more than you're willing to lose.
