Should Crypto Investors Rebalance Their Portfolios?

Crypto investors often spend a lot of time deciding which assets to buy, but far less time thinking about when their portfolio needs to be adjusted. Rebalancing means periodically changing allocations so that a portfolio doesn’t become overly concentrated in one asset after major price movements. For example, a strong Bitcoin rally could turn a portfolio that was originally diversified into one dominated by BTC. Rebalancing can help investors stick to a predefined risk level rather than letting market movements make the decision for them. But selling an asset that is performing well can be emotionally difficult. Is regular rebalancing useful in crypto, or does it make more sense to let winners run?
