I have $100k to invest. Tell me how I can invest it to make $800k in 1 year.

As the title says it all, I have around $100k or more to invest and I'm looking at how I can invest this sum and roll it to $800k within a year from now. I'm looking at something long term and sustainable and I'm exploring into cryptocurrency like bitcoin, ethereum, litecoin etc.

I'm looking to create my own kind of cryptocurrency and I'm looking at the features of Litecoin. I would like to set up an in-house fintech team or engage a vendor to do this project. Is this something feasible?…
