Would like to know where the STX tokens come from ?
The BNT is bought by the stox team right
Stx is a smart token itself.
Stox is a smart token using bancor protocol,
The Bancor protocol enables anyone to create a new type of cryptocurrency called a smart token, which can hold (and trade) other cryptocurrencies.
smart contract issues new tokens (expanding the supply) to anyone who purchases it with any of its reserve tokens, and withdraws tokens from the reserves (contracting supply) for anyone choosing to liquidate the Smart Token
Essentially, a Smart Token's price will always strive to balance supply and demand for the Smart Token, meaning that when it is being purchased, the price is climbing, and when it is being sold, the price is dropping, in relative proportion to the respective transaction sizes.
