What I need is simple, a system of deposit in guarantee for some system of forums where the users can load money to their accounts (bitcoin, altcoin) and open requests of deposit in guarantee with other members of the forum and can release disputes or cancel the event. I also need to have a feedback system Basically the idea is to create a forum where users can sell their digital products, if possible they can upload their material to the same forum. We will work with blocktrail api. On the other hand it is necessary that the system allows me to configure a fee per operation, by deposit and withdrawal of altcoins, bitcoins. that has 2fa is paramount, security is a priority. If a user wishes to become a provider or seller, he / she must pay a monthly, annual, weekly or a fixed time fee. On the other hand, I need to register a user must pay a fee for only once to reactivate the account alone. I would need this as soon as possible.
