Currently timing a $30K buy to bring my holdings to exactly 1 BTC

Bought .75 BTC in 2019 when price was around $6-7000. Recently been thinking it would be nice to increase my holdings to a whole coin because, why not? I'm convinced that the upside potential is promising. Just this afternoon, I positioned ~$32K and it's ready to deploy. My initial thought was just to place a market order for the whole purchase, regardless of price. I mean, who cares if I buy at $119K or $120K, right. Or, I could DCA over a month, or a week, or even a day. In the scheme of things, I know it's not a big deal, but does anyone have thoughts on how to optimize this purchase?
