I have four different ways I store my Bitcoin and two are a bit stupid. So we will start with stupid, I have some Bitcoin on exchanges for trading, I have a couple of Bitcoin in blockchain.info.
My profit from trading goes in a hardware wallet which builds up and when it gets to 10btc it is put on paper wallets, laminated and stored in a safe location. In the near future I am going to have 10-20 stored in private keys hid in tattoos. Of course for a extra safety that will be done in 2 parts, from two different tattooist just to be on the safe side of a photographic memory who knew about private keys. I like the idea of being basically naked and still having access to funds should the need ever come.
