Recently, I've been "evangelizing" proper practices for personal data security to 100s of people from the poker table to the dinner table the last few years.
Too often I'm horrified at the lack of understanding and carelessness so many regard this important topic.
My top three harping points are:
1) Disaster Recovery - Have a data recovery plan in case of total loss of your phone, laptop, house, etc.
2) Use a dedicated, and properly maintained "banking" laptop used ONLY to visit safe websites and applications, no email, no searching, etc.
3) Digital Estate Planning - Do your care what becames of your digital assets and accounts access in the event of your incapacitation or demise ? What is your provisioning for this unwanted, and inevitable occurrence ?
Now that more people are jumping on the Cryptocurrencies bandwagon, good personal data security has become even more complex, and more important !
The blog entry below, kindly authored by the helpful Hodor, is an excellent starting point...
Good luck, and ALWAYS backup
