If you ever wanted to make 500,000$ within two days (actually within 26hours), you should read THIS. All you need is a bit courage. Okay, also 200,000$. But It might work also work with 2,000$ (then you may make “only” 5k$ or 10k$ in 2 days).
Whatever, interesting question:
" I have $200,000 but need to turn it into $500,000 within a week or I will be bankrupt and the $200,000 will be lost anyway. What should I gamble on?"
