i mostly have my BTC on paper wallets in a safe, but i do keep a small amount in breadwallet just for showing people and send small amounts. I think for long term storage paper wallets or offline hardware wallets are the way to go, the difference being paper wallets are free, which i like 
I actuay store my bitcoins in my wallet. My application wallet on my android phone. It is an application named coins that you can store bitcoin and can convert into peso. I have also onlime wallet an eth wallet to be specific which can actually store my eth tokens or any tokens that i get in the signature campaign i joined.
