Portfolio Indexing is a strategy used by investors to trade and hold crypto indexes. Allocations, often done in percentages of each crypto asset, are represented in the total value of the combined portfolio. The act of rebalancing a portfolio involves the trading of coins such that the value held in each asset is once again equal to the percentages that were originally specified. Such bots provide traders with the ability to rebalance their portfolios. This is a process of realigning the weightings of assets in a portfolio to maintain the target allocation splits. Portfolio rebalancing allows traders to design trading intervals or set thresholds that help to maintain their target allocation to gain more control over their long-term risk-levels.
