Think of it this way. You could use the term "fund" if you want to compare it to a traditional fiat-type investment (with one distinction I'll outline below).
1 seat = 1 share in the "fund"
There's 30,000 possible active seats (shares) available in total in the "fund".
If the fund is able to raise 30,000 Satoshi, each seat would get a dividend payback of 1 Satoshi.
The fund attempts to grow it's total BTC holdings by several means. Currently the main sources of income are sales from physical silver cold-wallet type storage coins, and mining donations. Several people, myself included, run miners which donate some or all mining proceeds to the fund, which are then distributed as donation payouts to all seats. A Keno guessing game was just created which we hope will gain interest and bring additional income into the fund.
There are other things being developed which, over time, hope to increase the fund's income significantly, so that your eventual distributions are greater than what you put into it. By doing that, it should in theory increase the value of the seat you purchased which can then be sold for profit. For example, you can easily track what you put in, and what your value out is within the user pages on the website. According to my panel, I'm up about 7% value from what I've invested so far over the past 3 months.
The main difference here is that unlike many of the other "investments" you see around, the fund does not hold onto the BTC it takes in, rather each week a distribution is made to all seat holders for whatever BTC are made during the past week. This prevents a lot of potential issues other funds see, such as hacked or stolen hot wallets with all proceeds - no one holder has the main stash of BTC funds so it cannot simply be run off with by one person (or a group) thus leaving all the investors with a total loss of investment, etc.
I hope this helps answer your question(s) a little more, but please keep asking as you need to. There's plenty of people here who believe in seeing this succeed and are willing to help.
