I recommend hardware wallet. In any case, in case you're searching for a shabby choice at that point go for Mycelium or Bread wallet or a paper wallet. It’s the most secure on the grounds that it utilizes cool storage.
On bitcoin exchange by paying fee amount of transaction fee you can move to another currency. To make money when ever you want. It will give you profit and if you store your bitcoin in your wallet then it will give you nothing.
