NXT is scum.You need to put in 5 or more BTC's to forge something.In two months i forged 0 NXT with 19000 NXT in my wallet,and generated two blocks( 0 NXT each) Now I sold all my NXT and bought Yin & Yang coins!
That's forging in a POS currency. You can 'mine' NXT with hashrate.org, if you want POW experience.
