Yayyy!
I absolutely don't know... but I would assume that I would set the value of my own SMT. So, if I had 1000 Steem... and I wanted to create 1000 NINJAcoins, then they'd be worth 1 Steem each. If I only wanted to create 10 NINJACoins then they'd be worth 100 Steem each. That is my understanding, but I could also be super mega wrong on that one.
So, say that I created 10 NINJAcoins at the value of 100 Steem each (ie, I paid 1000 Steem to create these coins). I would then keep all 10 coins - but I could hold an ICO and sell them on an Exchange if I wanted to. I'd then keep whatever I didn't sell.
Then.... I could award creators with a NINJAcoin for the best ninja articles created for my website, or on Steem or YouTube or whatever... as long as they had a Steem account.
The work that Steemit is doing at the moment is developing the Steem wallet that we all have to be able to cope with potentially unlimited numbers of coins/tokens.
Thanks for the prize money! You're the best!
