Also - make sure to get a hardware wallet for your coins if you are holding a decent amount.
The Ledger Nano S (https://www.ledgerwallet.com/r/fed9?path=/products/1-ledger-nano) is what I have and it is so cool... 
My private keys are totally secured offline and no one has access even if my computer is compromised.  Absolutely no worrying about my coins being stolen!
