Usage?
The token can be used for payment transfer and purchasing.
Why anyone would use your currency while there are a lot of others crypto like bitcoin, eth, or even the coin you used to make yours, stellar? Will people use only because it is stable coin? I do not think that's happenig because other stable coin has already built themselves a big corner.
First, they need to create a decent website for merchant to consider them as alternative payment method.
And if this is another stable coin, do they have resources to back this project?
Right now, merchants are considering the popular cryptocurrencies only like btc or eth.
Stellar is not yet on their list, but they have more chance to be considered than yours.
