Fill out your info Now you need to make a deposit. You are not buying anything at this point, just funding your trading account so you can place trades as you wish. There are also minimum and maximum investments that are mandated by Banc de Binary, but these have a very wide range that should satisfy the most conservative traders and the big spending traders alike. The minimum investment is a low $1, which was as little as we have seen on any of our reviews. For those that are not afraid to risk some big money the maximum investment is $6000. I may be nuts, but I prefer to have reserves for my actual reserves.
