Coinbase and Robinhood: What $10 a Week Becomes by 2030

A friend of mine — smart engineer, IIT type, thirties — told me last month he "missed the whole crypto thing" and it was too late now.

I asked how much bitcoin was in 2016. He guessed $10,000. It was $400. I asked how much Coinbase was worth when it went public in 2021. He guessed $10 billion. It was $85 billion. I asked how much Robinhood was worth when it went public four months later. He shrugged. It was $32 billion.

Then I asked him one more thing: "If you put ten dollars a week into these two companies from tomorrow morning until December 31, 2030 — one skipped Zomato order every Friday — what do you think you'd have?"

He guessed a couple of thousand rupees. It's more than that. Meaningfully more. This post is the story of what that actually looks like, why I'm doing it, and what could break it.

Meet the two companies you're about to own

Coinbase (COIN) is the Wall Street of crypto. If you've bought bitcoin or ethereum through a regulated exchange in the United States, there's an 8-in-10 chance the trade sat inside Coinbase's system somewhere. They also make a ton of money on the boring plumbing — stablecoin interest, custody for institutions, derivatives — that most people don't associate with the brand.

Robinhood (HOOD) is the Costco of retail stock trading. Zero commissions. A phone-first app. And, unlike Costco, a business that makes money on volume, not membership. Started as a stock-trading app, now runs one of the largest retail crypto venues in the U.S., a cash-management product that pays interest, and a growing wealth-management side.

Two companies at the exact same moment in history: retail investors and crypto have stopped being separate categories.

Coinbase — the exchange that survived the 2022 crash still owns the field

Coinbase's story is boring in the best possible way. In 2022, crypto imploded. FTX collapsed in fraud. BlockFi filed. Celsius disappeared. Every centralized crypto business was under existential threat.

Coinbase kept trading. Kept processing withdrawals. Kept the U.S. Marshals and the SEC on speed dial. Never lost customer money. And came out of the winter with the largest and most trusted footprint in a category that's now ~$4 trillion in market cap globally.

Here's what people miss. Only about a third of Coinbase's revenue actually comes from consumers clicking "Buy Bitcoin." Most of it now comes from three quieter business lines:

• USDC interest — Coinbase gets a share of the interest on the ~$60B stablecoin float Circle manages. That's $3B+ a year of near-guaranteed revenue if U.S. rates stay above 3%.

Institutional custody — the BlackRock bitcoin ETF, the Fidelity ETF, and dozens of others custody at Coinbase. Fees are small in percentage terms, huge in absolute dollars.

Derivatives — Q1 2026 derivatives volume hit $4.2 billion, up 169% year over year. This is a business that barely existed for retail two years ago.

The stock trades around $210 today. The 52-week range is $139 to $290-ish. It's volatile like a crypto asset but the underlying business is diversifying into something that looks more like the NYSE than like a meme.

Robinhood — the app that ate retail brokerage now wants your paycheck

Robinhood has 27.4 million funded customers. That's more than E-Trade at its peak. More than Schwab had before it bought TD Ameritrade. And it happened in twelve years.

The company's fun story is that it made stock trading feel like Candy Crush. The real story is what came after. Once they had the customers, they added a bank-adjacent product: Robinhood Gold, with 4-5% interest on cash, retirement accounts with a 3% match, credit card, and now full wealth-management for people who don't want to talk to a human advisor.

The Q1 2026 net deposits number is the tell: $18 billion in a single quarter, growing at 20%+ annualized. That's not people day-trading meme stocks. That's people moving actual paychecks and savings into the app.

The stock trades around $78. It fell from $80 in late April on the Q1 earnings miss — revenue came in at $1.07B against $1.14B expected, and net deposits growth was seen as "just" 20% by an impossible-to-please market. The stock is still up meaningfully on the year and analysts have targets from $60 all the way to $110.

⭐ What $10, $25, or $50 a week becomes by December 2030

Now the interesting part.

Ground rules for the math. Start next Friday (April 24, 2026). Split whatever amount you pick 50/50 between COIN and HOOD. Buy fractional shares every single Friday no matter what the price is. Stop on December 26, 2030. That's 245 Fridays. Roughly four and a half years of not looking at the chart.

The three scenarios.

Bear — crypto has a long, boring winter. Rates stay high, ETF flows plateau, retail loses interest. COIN drifts to $175. HOOD drifts to $55.

Base — crypto normalizes as an asset class, stablecoin regulation passes cleanly, and Robinhood's non-trading products compound. COIN reaches $450. HOOD reaches $175.

Bull — tokenization of real-world assets takes off, prediction markets go mainstream, and Robinhood becomes a true financial super-app. COIN hits $900. HOOD hits $350.

The math on your $10 a week. You put in $4,900 total across four and a half years. Depending on which world you end up in:

Multiply everything by 2.5× for $25/week ($12,250 in → $10,600 bear / $16,800 base / $19,950 bull), and by 5× for $50/week ($24,500 in → $21,300 / $33,700 / $39,900).

In layman terms.

$10 a week. One less Zomato/Swiggy order. One skipped filter coffee if you drink specialty. Ten bucks. Base case, you walk out of 2030 with about $6,700 on $4,900 in. That's meaningful upside on money you'd never have missed.

$25 a week. One skipped Uber ride. One dinner out swapped for cooking at home. Base case, you're sitting on ~$16,800. That's the down payment on a decent car in India, or first-month rent in San Francisco.

$50 a week. One nice restaurant meal skipped, or two coffees a day traded for filter coffee at home. Base case: $33,700 by end of 2030. Bull case: nearly $40k. Bear case: still $21k, meaningfully more than what a savings account would give you on the same schedule.

The magic isn't the return in any one year. The magic is that you don't have to be right about which year is which. You don't have to time the crypto cycle. You don't have to guess when HOOD lists in India. You just keep buying.

What could break this

Three real risks to be honest about.

Crypto goes into an actual multi-year winter, not just a bad quarter. Coinbase revenue is still ~two-thirds crypto-linked. If bitcoin trades sideways at $60k for four years and altcoins bleed, COIN's stock probably trades in the $150-180 range and the base case gets closer to bear.

Retail interest fades and Robinhood can't monetize non-trading fast enough. Robinhood's growth engine right now is expanding financial services beyond trading. If the ex-trading products (Gold, credit card, retirement) don't hit critical mass by 2028, the multiple compresses hard.

Regulation shifts against both. If the U.S. reverses course on crypto-friendly rules — or if consumer regulation forces Robinhood to disclose more of its payment-for-order-flow economics — both stocks re-rate lower. This is a low-probability but non-zero risk.

I stop DCA and reassess if any of those three actually happen. Not because I predicted them. Because the world changed.

The reflection

Here's what compounding looks like in one sentence: the reason my parents' generation missed most of the tech stock story wasn't that they didn't understand tech — it was that they never started buying, and the price kept going up while they waited for the "right moment."

The right moment doesn't come. What comes is Friday, then Friday, then Friday. $10 or $25 or $50 goes in. You don't check the chart. Four and a half years pass. What you have is a number that was never going to happen from a savings account, and that you wouldn't have gotten from an FD, and that you definitely wouldn't have gotten from watching from the sidelines.

The two companies I picked here aren't the only right answer. They are, honestly, my picks — I own both — and the pattern applies to any well-chosen pair. What matters is starting, not what starts.

Skip the Zomato order. Buy the share. See you in 2030.
