Thanks for your interest. nTOPAZ tokens are not STEEM Engine tokens. It is ERC-20 token. The reason why we issue them on Ethereum is we will do IEO. Additionally, Many centralized exchanges prefer ERC-20 for IEO.
It depends on your STEEM Power equity. If you delegate 1,000 STEEM Power for nTOPAZ, you will receive around 5~7,000 nTOPAZ tokens. Because, the total # of STEEM Power delegate is around 110,000.
If you delegate 1,000 SP for nTOPAZ, you will receive $1 Upvoting each week. Once you receive $10 Upvoting for 10 weeks, you just get only nTOPAZ tokens.
