Crypto News & ICO Reviews
Honestly I'm surprised how many people is losing money by typing their exchange of preference in google and then going through a random link (phishing).
Every time you register at a new exchange / online wallet, BOOKMARK it. There's is less chance your browser is compromised, so this adds an extra layer of security. Using adblock also filters out those shady results from google.
Ultimately, ALWAYS DOUBLE CHECK everything (web address, bitcoin wallet) those few seconds of additional work are WORTH IT, even if you're storing a significant amount of money, don't be lazy.
For the rest, don't give any password that doesn't belong to the site you're currently on, no real website will ask you for this. And store your non-trading funds offline, if you're not trading then you're putting your money at risk for 0 benefits.
