EVERYONE NEEDS A TREZOR! Don’t keep your coins anywhere where the keys can be accessed! This serves as your impenetrable savings account. One of my favorite features is the way it offers the freedom to create multiple accounts for each coin, each with their own BIP49 XPUB. This is HUGE for sorting your coins into unique accounts, and when done properly, offers a huge advantage when it comes to tax reporting.
I absolutely love my Trezor. I find it extremely intuitive and easy to use with the exception of.....Ethererum. Ethereum is stored via MyEtherWallet which has a bit of an intimidating user interface. I also use my Trezor to store ERC20 tokens from ICOs. In the future I hope Trezor can adopt more coins in the top 10 market cap list.
