I would like to know how much is the possible amount of returns for binary options?

 

[Enivid]

With brokers that offer flexible binary options (for example, BetOnMarkets) the potential ROI is not limited as you can buy extremely cheap OTM options and earn thousands percents on them.

As Enivid said, there is no limit from the brokers side. I think you need to ask yourself what your limits are and be realistic. In theory you can take $20 and turn it into $1,000 with a few trades, but that is not realistic. I would recommend that you approach it with a realstic approach.
