Set a limit order. Cash app can do that.
But also just buy it. In 12-18 months you won't care if you bought at 36k or 37k.

Thanks for the info, I didn't know I could do that. Always seems to drop overnight, now I can set up an order and see what happens.
I also agree, won't make much difference when bitcoin is $100k or $500k or $1mil.
