My biggest success with binary options was 3600% profit in 3 weeks (15 days of active trading), the next time I invested I made 2900% profit in 4 days, but then I blew it. I can agree there are many brokers that are scam and this is the problem, but I have been trading for 3 years and I never had problems and I am profitable. I don't trade all the time, only occasionally.
I think that the best strategy, at least what works for me, is taking the high risk with high frequency trading and then withdraw the profits when you make for example 1000% profit. Then go back with minimum investment and try to repeat the performance.
I also just found out that a new platform is opening soon, that is not a broker, but a 'binary exchange' where you can trade against other traders. This is especially interesting for people who are afraid of scam brokers.
I haven't been trading for a while now, but this sounds very promising, because the return rates are also higher, and I think this is the broker I want to try out.
Will try to remember and post back my experience once this starts. You can get more info about trade equal here:
