System 4 — Robo Plus On-Ramp

Wealthfront, Acorns, and Coinbase. Two robo-tier venues paired with one regulated crypto on-ramp.

Who this is for

Readers who want a hands-off managed-investing core with a small crypto allocation.

System layers

  • On-ramp: Coinbase. Regulated US exchange used for the crypto sleeve.
  • Yield venue (managed investing + cash): Wealthfront, Acorns. Wealthfront for cash sweep and managed portfolios; Acorns for round-up automation. Two SEC-registered advisers with different fee structures.

Cadence

Quarterly review of both robo accounts; annual review of subscription and advisory fees against balances.

Why it works

The robo layer carries the system; the on-ramp adds optionality without changing the core risk profile.

What breaks it

Letting Acorns subscription fees eat into small balances. The subscription model becomes punitive below a certain account size.
