The smart contract:

1. Simulates leveraged trading returns for Ethereum without using debt. If ETH goes up 2000% this year, FUTR will rise approximately 25,000%

2. Allows merchants to progressively charge less for goods and services while earning more via employing a FUTR dollar (F$) concept which extracts the amount of FUTR in the current mining round and benchmarks that amount against the per unit value of ETH (e.g. Level 1 ETH is generating 114 FUTR which is a per FUTR dollar value of $9.14; the FUTR dollar is therefore $9.14 right now. When the next level kicks in ETH mines 89 FUTR and thus with ETH at $1042 the FUTR dollar would increase by 28% automatically to $11.07 - even without the ETH price moving. This enables customers to pay with less FUTR but the merchant to earn more in FIAT terms) as long as the merchant keeps prices stable and charges in FUTR

3. Recycles constantly - unlike securitized derivatives contracts once FUTR gets to the end of the 10-Level mining cycle all the FUTR swaps for all the ETH and the process begins anew. In practice of course not all FUTR miners / holders will swap for ETH at the end of the 13 months so it's likely the smart contract will build up with even more ETH the next year. Because of the Fibonacci algo in the contract the miners least likely to swap are the last ones to mine FUTR (unless ETH suffers a dramatic fall in value); this means that the unswapped FUTR will represent a slight increase in supply which will be reflected positively in the market cap but more so it will be disproportionately represented by a larger and faster growing share of ETH which will make all the FUTR swappers even richer next year than they were in this year.

Imagine if a futures contract - a contract to purchase - was a unit of payment. Imagine what it would do to supply-demand economics. That's the core wow factor on this one. In a very broad sense I guess you could call it a money machine. Whether this qualifies as useful or not is down to personal preference, but it certainly isn't "another token". It is likely in fact that the product has never been thought of let alone attempted. I hope this answers your question sufficiently.
