Each month Midas team makes a rebalancing for the index equaling the value of each coin to 20%. It means that if a coin increased on 10% in price, increasing its equite to 22% of the index, Midas will sell 2% to buy other coins, making the equal equities for all coins. It shows great results on long-term investment, since MNI is gathering profits and buys coins that lowered in value.
