>Money loves silence
This is great advice applicable everywhere
Yes, if someone will keep on posting rather boosting about his wealth on all social forums and websites, he better get ready for attacks. You cannot keep bees away from sweets for long once you have shown it to them. So, the lesser you open your mouth the better it is.
I think if you invest your money in Bitcoins and then you start trading, you have to be very much careful as there will be a lot of scammers who will be keeping an eye on your money and will be trying their best to take away your money. There will be no one else but only you who needs to protect his money at the time of trading.
