I would strongly advise anyone to not deposit any money with any binary options broker.
I was interested in binary options myself but according to my research all of those brokers are shady. They would either call you permanently (to make you deposit more money) and/or give a phony reason to not allow you to withdraw your money.
The only broker I know of that offers something similar to binary options and seems to be trustworthy is IG markets. They have something called digital 100s which is similar to binary options. I am in no way affiliated with them, I just want to help out.
By the way, at least in German, there are sites that specialize on comparing binary option brokers and compare how much they can be trusted etc. but they seem to cooperate with them / gain from affiliate links. Don't trust those sites either.
