If you really think that Nxt can be hacked pls go hack this account and make yourself a very rich man. -.-

I personally like the idea of a brain wallet really very much but in the end Nxt will have to change to a system with a local wallet.dat file because people are obviously too stupid to create save passphrase.

Btw: How many bitcoins are stolen? https://bitcointalk.org/index.php?topic=83794.0#post_toc_17
Is it bitcoins fault? No, either people are naive and sending stranger people bitcoin without escrow or they downloading so much porn on the same pc where they use the bitcoin wallet.
