On GNU/Linux (Kubuntu 14.04) bitmonerod takes 6,263,272 K so 8GB should be enough barely.

The security offered at the current Monero hash rate not being enough relative to the value of the moneroj being held would be one issue.  In other words, there's still always the possibility of someone coming along and deciding to fork Monero with a 51% attack, based on the amount of hashing power that Monero currently has. At least we're using a different hashing algorithm than Bitcoin, or people could've/would've gone at Monero directly.

This community is well recognize to troll and FUD other thread

In which thread is your post exactly? As yes, right...

It's funny that the correlation is SO FUCKING STRONG between monero price and the amount of trolls wasting time to post crap here.

Low monero price -> very high signal/noise ratio.
Higher monero price -> high signal/noise ratio, with obvious paid/interested crap in-between.
