Nope, a Bitcoin wallet address should really only be controlled by one person. If you're sharing an address, you're also sharing the private key that goes with it, and that's risky business.

For group control over funds without sharing private keys, multisig is the way to go. It gives each person their own key for joint authority over an address.

Sharing a single-key wallet? Not a great idea – too much trust needed and big security no-no! Keep your keys to yourself for peace of mind.
