What about NXT forging, is that profitable? How many coins do I need to own to forge anything significant ATM?
Forging is for securing the network, not for profit, it only brings 0.5% yearly, no more, with the current volume of txs.
So there is no way to mine NXT, forging brings next to nothing, why would I buy NXT then? If price speculation is the only thing I make money with NXT, this is not something I am interest in. After all, there are coins offering higher POS annual reward then 0.5%. If I miss something, please do correct me, quite green when talking about NXT.
Well, NXT is about building a decentralized economy, not just about speculation. For example, you can crowdfund your business at NXT Asset Exchange, it's one of use cases. But you can mine NXT too, at hashrate.org if you're into mining business. I can't tell you why you should buy NXT or this or that crypto, you have to decide for yourself. Check out nxtforum.org and you might get some ideas from what other people already do with NXT.
