Why store a third of them on a web wallet? Desktop and hardware wallets are way safer. First of all, web wallet websites are owned by somebody or a corporation. That means there is a possibility of them scamming at any time. Even Blockchain.info can close at any time and have all the money that is found in every wallet there. While this can be happening with web wallets, desktop and hardware ones, unless hacked, cannot be vulnerable to such things. There is also the option of having a paper wallet which is the safest in my opinion: your money is stored on a small piece of paper that's printed offline for security against hackers or keyloggers, and nothing can happen to them.
