Pocket Option Official
Binary No Deposit Bonus (Binary Options) or commonly called (No Deposit Bonus/Welcome Bonus/NDB) is a promotion organized by a brokerage company that gives you a live trading account with a free bonus balance, so you can trade and connect to the real market in real time.
Is Pocket Option cheating? Pocket Option is not a trusted broker because it is not regulated by a financial authority with strict standards. We would not open an account for ourselves with them. If you want to stay safe, only sign up with brokers that are overseen by a top-tier and stringent regulator.
