That's because any idiot with 6 months training can churn out simple Java apps...
But it takes a university education... and many years of experience to be a competent C++ engineer.
Decentralized java crypto platform, like NXT, isn't exactly a simple Java app, and if it lacked security, someone would have broken it already

It has only been around for
6 months, give it time. If a hacker wants to attack a coin are they going to try to tackle a coin with military grade security (EXO) or noob grade security (Nxt).
It WILL happen. It is just a matter of when.
Correction there, comes November 24th Nxt will be celebrating 1 year. So its 12 months in existence. If someone CAN hack nxt, they would have done it already. All the big account holders is open for anyone's view.
So... keep talking..
