The original SPI fund value was hard-capped at 100,000 tokens sold at .13 USD (1 HIVE each) approximately six years ago (7,000 SPI have been burned since). I know you were looking at income, but that isn't really a fair comparison for SPI which is an investment and growth token. The dividend or income is a bonus. An earnings and holdings report is usually published on a Sunday under the @spinvest account. In the last report, each SPI had a value of 5.01 HIVE and 2.61 USD.

With regard to liquidity: uniquely, as far as I am aware, SPI has a 95% buyback guarantee. Holders simply need to apply to @spinvest saying they want to use the buyback guarantee and how many SPI they want to sell. The buyback is accomplished within a matter of days and has managed buybacks for over 11,000 SPI at a time without a problem. (I also have a buy wall available on Hive-Engine for anyone who wants to sell SPI).

SPIs are re-circulated through a subscription savings plan managed by the Saturday Savers Club over on the @eddie-earner account, the home of EDSI, SPI's savings and income token. The subscription savings plan takes advantage of the recurring payments feature to automate payments over forty weeks, spreading the cost of purchasing SPI so that even the smallest accounts can enter the fund at 1.5 HIVE or less a week. The next SPI subscription plan will launch mid-March and open at the beginning of April. Details will be available on the @eddie-earner account.
