Using the "Vault" or "Cold Storage" feature, which makes the user's bitcoins securely stored in systems that are not connected to the Internet.

Xapo Wallet really takes security seriously and so is a very secure wallet to safely store bitcoins. It's very easy to use Xapo Wallet to send and receive bitcoin. I also like the cold storage feature that can be used to save bitcoins for a long period of time. It provides even greater protection for my coins. 8

In the modern crypto sphere it's good to have your portfolio spread not only across multiple coins, but across multiple wallets too for that added layer of security. That way, one compromised wallet isn't the end of the world. It is basically a comptitor for coinbase, which I highly approve of. CoinBase's questionable business practices (BCH launch -.-) and monopoly over this industry has gone on long enough, and apps liek Xapo come along and are a real threat. Lower fees, quicker transfer times and I don't feel scared to use is (coinbase has locked me out of my account numerous times, which is a worry, as although I've gotten it back each time there's always a risk that I won't). Good customisation and a clean, simple and intuitive user interface makes this app a winner for me.
