BTC. Buy 500 days before halving, sell 500 days after halving.
For 10x with BTC in 2025 is a bit late, but you can still do it. Either 10x futures, or something even simpler, like a 12x moon future grid bot. Don't laugh, it makes me even more profit than being awake and trading sleepless nights for less alpha.
Expert mode: Use the leveraged bear future grid bot strategy for the bear market. Everything less than turning 30k into a mio. during the bear I'd classify as an absolute failure.
