Bitcoin is currently trading in the high demand zone 36k,35k,32k, 28k are significant level to watch, so since you were targeting to initially buy around $40k and futunately for you the market has given you a discount ( cheeper price ) to get in,
I suggest you do dollar cost averaging DCA from this point in market and set up your buying price base on the aforementioned price level, even if the price in case drops lower, it also means another better opportunity for you to buy.
Lastly buying the dips comes with amazing rewards at last #Buy and HODL.
