if you dig deep, ther are good and bad reviews of any broker

Ctoption is one of the best binary platform. No issues at all. Withdrawals processed within a day. No manipulation with the prices compare to other platforms where almost every one of them play tricks with the price so you loose money if you are not aware of that. The only drawback is if the price moves to fast you will not be able to place trades you will get an error. So the platform is not good if you trade news.

Been using CTOption for hedging purposes, they have higher payouts on some assets than other brokers (85% comparing to 75-80% with other BO brokers). Made around 8 withdrawals from them, no issues so far.

I joined recently CToption, so far i like the flow of their execution, and the services provided is good, i am a skeptic person, but so far i have not encounter anything out of the norm, I will check back here after I make my first withdrawal.
