A few months ago I created a token called RARE. The intent being only 100 will ever be minted. A precision of 0 means they cannot be split into fractions. A token is always one.
Today, another RARE Token has been released here for 50 STEEM. Every new token minted, the value of future released tokens will increase. The first was sold for 5 STEEM. This one is 50 and the next will be more.
I haven't worked out particulars, but the intent is token holders would get benefits (upvotes and other perks for holding a RARE Token).
First come first serve. A new token will be minted at a later undetermined date.
