How do you secure your Bitcoins?

[missfox]

I have been doing research on securing bitcoins in wallets and I was wondering what everyone does. I am currently using a few paper wallets. I don't really like it because it's a one way street if you want them to be secure. I was looking at the ledger nano s and was wondering what people thought about it. How many bitcoins can it hold? Should I wait for the ledger blue? any opinions will be greatly appreciated.
