What in consideration that it should have only 50% manageable by user, why don't just give the user/customer all the ability to manage their own coins.
As of yet, the AVG 50 is free to use and all the information about the portfolio components and how to build it are in our whitepaper. This was done to act as a "trial" product and also expose the current state of the market where most other companies that have indices claim to provide a "safe" investment and diversification while in fact they do not.
50% of the AVG 50 is currently designed to hedge (go against) the other 50% highly correlated cryptocurrency exposure. This is done in such a way to mitigate the market downturns whilst still remaining competitive in bullish periods. This is not to say, however, that the current weights (% allocations) in each asset will remain the same. In fact, especially in the cryptocurrency market, factors tend to shift rapidly and so should the AVG 50 react to suit the current movements.
Finally, we will be rebalancing the portfolio and the updated version will be available on the 5th of April. It will be still free to use.
