The only way to celebrate the bitcoin halving is by hoarding or by taking a long position in the derivatives market. I see no other ways to celebrate really! The real celebration would happen when the price will reach ATH. Even though it looks hard at the current gloomy economic situation but Bitcoin is very unpredictable. Expect the unexpected!
I like your idea. For this purpose, I started studying bitcoin to take risks. For many, this doesn't look very reliable, but I think there will always be growth after a fall.
I'm celebrating by trying to use the lightning network to avoid the crazy high on chain fees!
