user7205: What is the minimum age a person must be to use the Bitcoin service?

user6679: Unless you are a miner, you do need to buy Bitcoins; and given the currently limited range of Bitcoin-only services, you do need to sell Bitcoins as well.
While neither buying or selling Bitcoins has an explicit age restriction any more than holding and spending pocket money at a car-boot sale does - if you buy or sell Bitcoins from a bank account you will be constrained by the age restrictions that may apply.

user153: Some merchants, exchanges or E-Wallets even may have age restrictions, but Bitcoin is a protocol and therefore there is no restrictions regarding how it is used.

user7157: There is no minimum age, my children have Bitcoins and have for years.
Service by service should implement whatever safety or age restrictions they need.
I am not aware of any work done on this front, perhaps somebody else can enlighten.
