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.
For most users mining brings less than zero. Leased forging is free and therefor offers a 100% guarantee of not having a loss in terms of NXT.
If a coin PoS-coin returns higher than NXT it has to have one of the following
1) Inflation (which means your return probably is real terms is actually 0 as you are only keeping up with the rest of the network)
2) Higher transaction fee
3) Higher transaction volume
If it has #3, that might be a good thing. But I don't know of a PoS-coin that has higher volume.
