On the 21st day of every month, Bit20 runs an algorithm that creates its new composition. By this process, it always includes the most promising coins. Some coins appear in the index and others disappear. Some of them gain weight and other lose some of it. This new composition swap with the previous one without any disturbance of the index price.
We have run this operation yesterday. Here is the new composition of the Bit20 Index Fund:
