Regarding your bet I've also bet on those ranges but only a small amount onto the 35k-37.5k range as a small insurance and my main bet is on the 40k-45k one. Odds are very good this one up to now fortunately.
Not a bad idea to keep one bet as insurance in case the previous one drops. Something like a derivative to cover your loss on the asset. Regarding bitcoin price, I think an untrend can push is upto 45k but beyond that a further rise might see a correctional downtrend first. On the lower side, below 40k will see buying pressure.
I also did not know that betting on Oscars was a thing here, if so that is pretty cool indeed. I was rooting for Oppenheimer and to get all sorts of prizes this year, but it seems people's interest is elsewhere, but its fine though.
