Why portfolios drift

When one coin rises faster than the others, it becomes a bigger share of what you hold, so your portfolio carries more of that coin's risk than you planned. Rebalancing means selling some of what has grown and buying what has fallen behind, to get back to the mix you chose.

Rebalancing with new money

Instead of selling, you can put new money into the holdings that are below target. That avoids selling, which can mean fees and, in many countries, tax on gains. Every trade has a cost, so many people rebalance on a schedule or only when a holding drifts a set amount from target.
