Female PhD's first round of coin trading plan, initial capital 2000u, currently 2459u, thanks to Ethereum for shorting and then going long, let's go!

The first round of the female trader's coin flipping plan, with a capital of 2000u. Currently holding a short position in Ethereum, the goal is to first hit 4000u. There's no choice, the borrowed money cannot be recovered now, and other funds will only arrive next month. I can only use 2000u for now.
