I will be Honest that this is my first time to be a freelance job if I win the Bid, I'm a Tech-savvy, a Retail Trader (Forex trading and Binary, Future Stocks Trader), Why I bid because I know I can help you with that, So please le let me help you. What I can do is search for that and do some personal Survey to other traders I know and ask them what they were using as the prepaid method for payment, as a trader also I also have some experience in using some prepaid method. So let me help you with that Sir/Madam. You can pay me on how much you want. Thanks
