So far so good - together we did pointed and spotted most important security steps which will help us and others to stay safe.
Thanks to all of you for responses and we are still waiting for some more!
So what is your way of checking the coin?

I posted a lengthy response to someone asking about a specific coin, I hope you'll excuse me for quoting it in full here but i) I've found that stuff-behind-links tends to stay there and play little part in the discussion, so I've adopted a strategy of transclusion and ii) I'm just a saddo:
Great Analysis!
Viz.Indeed great Analysis.
Many of the altcoins are just forked - but perhaps if someone just copy other coin and change just literally few lines in the code he is not reliable and his coin wont success. Which is a good thing to know before getting any of those coins.
cheers!
