Journal · The €50 offer

How large should a first crypto deposit be?

The right first deposit is the one you can watch fall by half without inventing a new personality.

Search results love a number. The honest answer is a test: if this euro amount went to zero, would your rent, your buffer, and your mood survive? For a great many salaried readers in Europe, €50 passes that test and €5,000 does not. The point of the first deposit is contact with the machinery — an account, a fee, a price that moves — not a transformed net worth.

€50 is also the figure in the referral this desk publishes. That is a coincidence you should notice, not a cosmic hint that fifty is the optimal portfolio weight. A promotion can match a sensible teaching size. It should not set your ceiling.

Three tests before the transfer

Test one: the emergency buffer already exists, or this deposit is not coming out of it. Test two: you can describe the asset in two sentences without the words “it can only go up”. Test three: you know the order you would follow if the price fell 30% next month. If the order is “panic and add money you need”, you are not depositing. You are auditioning.

Write the amount in the note next to the date. Future reviews get easier when the first line is plain. “2 Oct 2026, €50, learning deposit, not the plan” ages better than a screenshot of a candlestick.

Where the €50 offer fits, and where it does not

Robinhood’s EU crypto referral, as we state it: if you use this link to sign up and deposit at least €50, you'll receive €50 worth of crypto as a reward. Read the live terms. Eligibility, countries, the asset you receive, and the definition of “deposit” are not decided by a blog.

The offer fits a first deposit that was already going to be about that size. It does not fit a reader who must stretch past the buffer to hit a threshold. Missing a promotion is cheaper than funding it with rent. There will be other months to buy. There is a separate note on what “worth of crypto” means when a reward is described that way.

What to do the week after

Do not add a second, larger deposit because the first one felt easy. Easy is the sales environment working. Wait for your actual DCA date. Look at the fee you paid. Look at whether the euro amount and the coin amount both appear in your history. If the app is confusing, that confusion is data. Small size is what makes the data affordable.

Then go back to the rest of the portfolio. A first coin does not retire the three-bucket structure. If anything, it makes the ceiling more important, because now there is a number on a screen asking to be grown.

If you already know you want more than €50

Then the first transfer can still be €50, and the rest can arrive on later dates. Splitting a decision is not timid when the asset is volatile. It is how you discover whether you actually hold through a red week. People who deposit their full intended amount on day one often meet their real risk tolerance at the worst possible time.

Larger size demands a written ceiling and a reason that is not “the reward matched it”. Rewards are flat. Risk is not. Past €50, you are no longer in promotion math. You are in position sizing, and that essay is stricter than this one.
