Binary options trading best broker reviews and company
They are called Binary Options because the outcome is either win or lose, theres nothing in between. Another example is if you think the BTC price will go down. If the price at the expiration time is lower than the original price, you earn the options payout.
If you study binary options in detail you will see that the trading platform will always have an edge over the investor (you need to win over 50 of the time just to break even).
