my ip is dynamic, i'm not worried about that, being a target or not, they still need to find a way to infect me, which mean that they need that i download something or click on something, almost impossible
i think if you are really careful and know what your are doing, you are the best antivirus of your desktop, but i agree that such thing isn't advisable, average joe don't have the patience for something like this, they can not manage their own security
if you have 0.0001 btc of course your safe cause no one will work hard to stole your money.
but if it's 5 BTC even if your ip is dynamic or you have a cisco guard firewall. or DDos protection system or anything else.
the problem is your post, this post got 500 views maybe anyone will try to get your ip address.
if a hacker know that he will get 5 BTC (1100$). you know!!
