It seems to me that keeping the results of 50 coins in the 1st coin is somewhat risky. If more than 50 percent of the coins in the aggregate, or if the proportion of these several coins in losses will exceed the incomes of others, then you will still be in the red, and it is difficult to control 50 coins at the same time.
The risk metrics used for the C50 index are based on certain criteria. It isnt based on the top 50 coins, but the C50 Index is based on 50 coins that met our requirements on a quarterly basis. The correlation of the coins in the C50 Index are watched closely so all coins in The C50 Index wouldn't move according to how the overall market moves. So, for example, the C50 Index might be up for the day, but 45 coins in the index might be down for the day. Thank you for the question.
