You wouldn't have lost any profits if the pool you admin was secure, not pointing fingers just stating facts. If the pool makes roughly .007 for example BTC per Mhs and you get for example 2% of that per Mhs on a site with 1000 mhs your making good money per day. Its pretty easy to see if you were not making a good profit you wouldn't do period, nobody works for free or for little to no profit no matter how good of person you make yourself out to be.
Secure? How secure is secure? What world are you living in? - some bubble world where everything goes according to plan all the time? Maybe you're too young to appreciate that the world isn't always going to be how you hope it will be? Maybe you're old enough to know better but just want to have a moan?
Whichever it is, you really need to chill out and stop pretending that you're the expert and that everything would have been fine if people had only listened to you - you're such an expert after the fact, aren't you?
Organisations get compromised all the time, even organisations that spend massive amounts on technology and security, so you need to take a reality check, climb out the basement for a minute and if you can't manage to take a walk, get some fresh air and clear your head, then just point your browser here:
