Paper Wallet. A paper wallet is also a relatively safe way of storing Bitcoin, although it requires a bit more advanced understanding of how digital currencies work. Generate a paper wallet online using any number of dedicated websites, or generate the wallet offline for even greater security.
LOL, if you want to use paper wallet, I want to ask you a question. Why do many countries use credit card to replace paper money? Because bring paper money or store it is more difficult and not security as credit card. So, instead of use paper wallet, use offline wallet and store it on which device can store data is enough.
