I have been with binary.com about 7 years now. Have no claim about them. Only thing is that bots never work in real account there. So don't use them. Volatility indexes pairs are absolutely randomly generated, so they could be easily manipulated. Trade them as you trade any forex pair, don't expect some miracle there. Very easy to make money there but the same is for losing money. After all, no any issue with depositing and withdrawing money.
