When I first heard about bitcoin, my questions were:
1) Can it possibly work (do the ideas for how it works make sense)?
2) Is it a scam?
3) If it is not a scam, could it open my computer up to viruses/trojans if I run it?
LOL. Paranoid. First of all that has nothing to do with 'fear of bitcoin/altcoin/jokecoin/scamcoin'. That's standard Inner Tube safety.
If you have to mention those issues, your audience isn't tall enough for this ride.
1) Reading and understanding Satoshi's whitepaper. Then thinking about it for a day or two and reading it again.
2) Finding out everything I could about the project. I read every forum thread here (there were probably under a hundred threads back then) and read Satoshi's initial postings on the crypto mailing list.
3) Downloaded and skimmed the source code to see if it looked vulnerable to buffer overflow or other remotely exploitable attacks.
That sounds like a procedure for both evaluating and IMPROVING. I still fail to see the need to mention of the 'fear factor'. Not calling you FUDmonkey, but this is kind of standard isn't it or should we require an internet driver's license?
This is where we're playing games with psychology or at least it can seem so. There's a lot of ppl with internet war stories talking about scams without context (exception silly coin from the hunter of the RealSilly).
1) Run the software in a virtual machine or on a machine that doesn't contain anything valuable.
2) Don't invest more money or time than you can afford to lose.
3) Use a different passphrase at every exchange site.
More boilerplate advice. It's good stuff for noobs, but come on are we still in 1990?
