This is actually dependent on the agent. You can do transactions until the amount you have as float. The more money the agent has as a float, the more money the agent can turn over. For example, if you have a float of only N50,000, as soon as customers have withdrawn a total of N50,000 from you (and transferred the same value to your account), you will have to go to the bank to withdraw that cash again as a float. So the larger the amount you have, the larger the number of transactions you can handle.
