Proposal description: With one of the goals of the ETF being to increase SIDX liquidity, it makes sense to have the ETF portfolio hold a portion of SIDX liquidity. This proposal aims to do three things. First, the liquidity pools in the main SIDX portfolio can be combined so that we're no longer separating initial and additional pools. This will make it easier to see exactly where our liquidity is going. Second, we will add SIDX liquidity to the ETF portfolio. The SIDX liquidity should make up a constant 25% of the ETF portfolio and be made up of the same allocation ratio as the main portfolio (62% Mistswap, 22% BlockNG, etc). Finally, the earned rewards for the ETF portfolio will just be compounded each week into whatever they were earned from, so the ETF funds are effectively automatically compounded weekly. The portfolio can also be rebalanced weekly to keep the SIDX liquidity allocation at 25%.
