You could set up a company with shareholdings and directorships. Might cost a bit more to set up and administer, but then you know who owns how much, and it's a legal entity for doing your share investing or share trading with. If a member wants to cash out you could just liquidate their portion of their shareholdings and buy them out then cancel the shares.
If you did it as an informal club and there was a dispute as to what someone contributes or otherwise, it could get messy.
