If you are new to the Bitcoin there are 3 most important things to remember if you want to stay safe when using bitcoin.
REMEMBER !!!
Rule no1: just like McAfee says - your smartfone isn't safe place to hold your bitcoin at all, so dont keep it there!!!!
(even if it's a McAfee phone)
Rule no2: use all possible security options when holding your bitcoin or other crypto-currencies on trading platforms
I can recommned you a safe trading platform BITBAY, you can register by clicking this link https://affiliate.bitbay.net/36718
for example: use 2-factor security with google authenticator
Rule no3: when you decide to store some bitcoin or other crypto-currencies, simply store them in your harware wallet
or paper bitcoin wallet
These 3 rules are your absolute basics to stay safe.
