I have tried to look into their code
Keep trying. JeanLuc made it a piece of art, leaving competition way behind.
Nxt 1.0 is Professional.
Nxt 2.0 will go Enterprise, providing a service for companies blockchains.
No enterprise is going to use your shit coin. Credits.vision, Ethereum, Lisk, and 50 other projects are light years ahead. This is nothing more than a P&D. In fact no enterprise wants to deal with these tokens so Lisk and Ethereum are out as well. They will go to Hyperledger and more professional groups. To think "enterprise" is going to use your ICO coins.
You should then leave this forum ?? or maybe do your own research cause what you are saying is BS.
