NMX token is an ERC20 token that NuMoney Exchange minted as a token for fee discounts for future transactions on NuMoney Exchange.
These tokens are then sold on NuMoney Exchange token to bootstrap the exchange's liquidity.
You can use them as a substitute for transactional fees on NuMoney Exchange.
For example, should you make an buy order for Monero on the ETH-XMR (Ethereum / Monero) market. You can choose to pay it in NMX tokens at a huge discount instead of paying a hypothetical 0.2% fees in ETH.
When the tokens are used, they are consumed and taken out of circulation from the open-market (and burnt).
NMX token lets you pay for 3x of its own value in fees.
For example, if 1 NMX token costs 1 ETH, you can choose to use NMX token to pay off 3ETH worth of fees.
The equivalent value of the token can be found in the [coin] / NMX market. For example, we will use the last order in the ETH-NMX market to get the equivalent value for NMX in ETH.
Here's a full example:
You can transfer your NMX tokens out of NuMoney Exchange after your account is verified.
You can trade it externally on Etherdelta, or any 3rd party exchange that lists NMX tokens.
