Here is some very very high risk, high reward proposition: growing $10 worth of Bitcoins to $1,000,000 worth.
And that’s with the BTC price remaining at 10,000 USD!
Although it does not make sense mathematically, I have been earning 1% every day for more than half a year already now.
I took out most of my profits so far and decided to continue playing with a very little amount, 0.001 BTC ($10 at BTC/USD = $10,000).
If I manage to do this for 3.2 years straight (very very unlikely) I will end up with a cool $1,000,000.
