All members are telling you that investing all your money is risky and their argument is "never invest what you can't afford to lose".
Well, i recommend you to invest all your money since you mentioned that you keep it in a bank and not using it. I believe in different quotes like "big risks, big reward" and also keep in mind that "He who risks and fails can be forgiven. He who never risks and never fails is a failure in his whole being".
