Mid career.
Ages 35 to 50.

Catching up if behind

If you arrive at 40 with less than one year of expenses saved, you are behind - but not dead. The fix is less glamorous than the internet suggests: spend less than you earn, aggressively, for the next 15 years.

• Target a 20 to 30% savings rate minimum. 40%+ if you are seriously behind.
• Catch-up contributions begin at 50 - an extra $1,000 per year on the IRAIndividual Retirement Account (IRA)A personal retirement savings account with tax advantages.

• Trade a newer car for a reliable used one. Direct the savings straight to investments.
• If you own a house with equity, you do not need to move up. The paid-down mortgage in your 50s is the point.

Kids and money: 529 vs Roth vs taxable

The default advice to dump money in a 529 is often wrong. Roth IRAs and taxable brokerages are more flexible. The honest comparison:

Bitcoin is not a good college vehicle. The timeline is too short and the volatility too high. A child born today needs the money in 18 years. Bitcoin over 18 years has historically done well - but any individual 18-year window could be flat or negative.

Mortgage payoff vs invest

The answer is mostly determined by your mortgage rate. The simple decision rule:

In between 4% and 6%, this becomes a partly emotional decision. A fully paid house in your 50s is a form of insurance on your lifestyle that spreadsheets cannot capture.

Disability insurance: the most underrated gap

Most people at this stage have plenty of life insurance and no disability insurance. That is backwards. You are roughly 3x more likely to become disabled than to die during your working years.

Employer-provided long-term disability is a decent start, but it often covers only 60% of base salary, not bonus or commission, and the benefit is usually taxable. For households that rely on the primary earner, an individual policy on top is worth pricing out.

Bitcoin as inflation hedge at this stage

A 5 to 10% Bitcoin allocation is a defensible position for a mid-career investor. Big enough to matter if BTC keeps doing what it has done. Small enough that a 70% drawdown does not derail retirement.

If a bull run pushes your allocation past 15 to 20%, rebalance back down. Volatility is the price of the upside; rebalancingrebalancingBuying and selling assets to restore your target portfolio split after market movements cause drift.Full definition is how you bank it. See Bitcoin Strategy.

Estate planning becomes non-optional

Once you have kids or a home, basic estate documents stop being optional. This is the minimum set:

1. A simple will naming a guardian for minor children and an executor for your estate.
2. A durable power of attorney covering finances.
3. A healthcare directive / living will plus medical power of attorney.
4. BeneficiarybeneficiaryThe person or entity you name to receive an account or insurance policy when you die. designations on every retirement account and life insurance policy. These override your will - check them annually.
