With crypto currencies become more and more common place, personal computer security is becoming far more important.
The security measures we used in 2012 are no longer good enough to keep yourself safe today.
For a little insight into how easy it could for you to get pwned, try plugging your email address into haveibeenpwned.com
If any results come up this is a sure sign that there are potential attack vectors for hackers to take control of your market accounts, online wallets or email addresses, especially if you use the same password on any two services.
Consider making sure you use different passwords on different services and back your passwords up using an encrypted program like KeePass or DashLane.
Stay safe out there :-)
