I don't like having to hold my hand over my pocket the entire time, it's a pain. I don't like to carry that much money on me, but even credit cards especially are dangerous to lose. The people who pickpocket have a system where once they get your cards they can do the damage they need to in a matter of minutes, before you even realize your wallet is gone.
Don't be stupid, get a pocket wallet and protect your stuff! Use moving blankets to keep them safe!
