Portfolio rebalancing is a strategy that has been used by investors for decades. First, an investor must determine how much of their portfolio they want to allocate to each asset. In the case of cryptocurrencies, each asset would be a coin. These allocations are simply the percent of each coin that should be represented in the total value of the combined portfolio. When it is time to rebalance the portfolio, the coins are traded such that the value held in each asset is once again equal to the percentages that were originally specified.
