The price has been going up quite steadily the past few days. I want to buy around 3k of coin but I'm reluctant right now, because I predict a crash happening quite soon. Not really sure where I should enter at, I think after a price drop of $50 I'd be safe.
Ideally I'm trying to win at a January 14 scenario


As long as bitcoin price stays above 200 SMA on a weekly chart we are in a bull market by definition.

If you want to get the best entry price just wait for a day with heavy selling volume and buy. Or you can just buy now at market. I think 6 months from now there is 80% chance price is over $500 so entry price may not be that important to you on a longer time frame.
