A lot of people are buying crypto currencies and not keeping it safe. Personally i'd advise you to keep majority of your portfolio offline to keep your assets as safe as possible. People need to remember you're your own bank and hackers are buzzing bee's so you have to keep you coins as safe as possible
What i recommend?
Firstly id recommend you always download the offline wallet for the currency you're buying. To make it as hard as possible for hacker to ever get a hold of your coins you need to encrypt your coin on your laptop and you password should be at least 12 characters. once you've stored your currency on your laptop back the encrypted copy up on two spare usb sticks and keep one available for day to day use and store your other usb in a hidden safe place
