That's how I made 172 dollars yesterday .. I have been buying bitcoin at very low prices (many times the order doesn't execute, but I always win ..

This is called Dual Investment.

I place a buy order for example at 89 thousand dollars and two things can happen

1. BTC goes down and I buy at 89 thousand and earn interest

2. It doesn't go down, I don't buy, I keep my dollars plus interest.
