You can try dual-currency arbitrage during the stage where Ethereum is leading the rise

For example, take out 500u and sell the big pie
If you go long with 500u ether, you can earn tens of dollars after deducting the handling fee. If you are lucky, it will cost about 100 dollars
Leverage should not exceed 30 times, lest you miss the pin and explode your position
Multiple backtests, research first, experiment later
