Core and Satellite: Building a Crypto Portfolio That Lasts

Core-satellite splits a portfolio into a large, steady core and a few small bets. How to apply it in crypto, how big the satellites should be, and when to rebalance.

Core and satellite is one of the oldest ideas in portfolio building, borrowed from institutional investors: hold most of your money in a large, steady core, and keep a small part for satellites, the higher-risk ideas that could do much better or much worse. It fits crypto unusually well.

The core

The core is what you would be comfortable holding through a full cycle without looking at it. In crypto, that means the assets with the longest history and the deepest markets, the ones least likely to disappear. For most people, that is Bitcoin, and often Ethereum next to it.

The core is where the well-known crypto habit of "HODLing" belongs. The word comes from a misspelled forum post in December 2013, "I AM HODLING", written during a sharp fall by someone who refused to sell. It stuck because it describes a real strategy: buy an asset you believe in for the long run, and do not trade it on every move.

The satellites

Satellites are the smaller bets: altcoins, newer projects, a thesis you believe the market has not priced yet. They are there for upside, and they should be sized for the likely outcome, which is loss.

The numbers are harsh. Between the 2021 and 2025 cycle peaks, only about 3.5% of the altcoins in our database gained ground on Bitcoin, and the median one lost 95% against it. A satellite has to be small enough that it going to zero changes nothing important.

How big should the satellites be

There is no universal answer, but there is a useful ceiling. Our investment plan caps the high-risk slice by the risk level you choose, and shortens it further on horizons under a full cycle:

Risk level Satellite cap
Low 2%
Medium 5%
High 10%

It also shows what you would lose if every satellite went to zero before it shows the amount to put in. If that number makes you uncomfortable, the slice is too big.

Rebalancing

Over time, one side outgrows the other. A satellite that runs up can end up a quarter of the portfolio, which means your risk has changed without you choosing it. Two common rules bring it back:

  • Calendar rebalancing: once or twice a year, trim what grew and top up what shrank.
  • Threshold rebalancing: act only when a part drifts past a limit you set, for example when the satellites pass twice their target share.

Rebalancing can trigger taxes and fees, so fewer, deliberate moves beat frequent ones.

Putting it together

  1. Decide the core first, and the amount you can hold through a bad year.
  2. Give the satellites a fixed share, and choose them with a stated reason and a stated risk.
  3. Add to both over time, for example with dollar-cost averaging.
  4. Rebalance by rule, not by mood.
