This seems to be very confusing. You're pre-programming the rates. What if there's no one available on your platform to buy your alpha or beta coin at the price set by your system? How would one cash out in such a situation?
Their will always be plenty of people trading on the platform at any time. I assume you mean cash out from aloha or beta to fiat? It doesn't matter if their is 1 trader active or 1 billion traders the end result is the same, cashing out is the simple process of converting the cryptocurrency inside our banking platform and having instant access to "real money" in your account which you can transfer to a local bank account or withdraw or make purchases with your Alpha debit card.
