Fee-share calculator
What makes small amounts look bad is never the fee rate — it is the fixed costs that do not care how much you put in. This tool exists to show you that directly.
Three typical routes compared#
This table is the static version of the calculator above, using three of the most typical routes. Read it looking for one thing: going down each column, does the number change?
| Amount in | A: transfer + spot left on the platform |
B: card purchase left on the platform |
C: transfer + spot + withdrawal withdrawal fee taken as 100 |
|---|---|---|---|
| 100 | 0.1% | 2.0% | 100.1% |
| 500 | 0.1% | 2.0% | 20.1% |
| 1,000 | 0.1% | 2.0% | 10.1% |
| 5,000 | 0.1% | 2.0% | 2.1% |
| 10,000 | 0.1% | 2.0% | 1.1% |
| 50,000 | 0.1% | 2.0% | 0.3% |
Columns A and B do not move at all — they are purely proportional, so buying 100 and buying 50,000 are charged the same share.
Column C falls from 100.1% to 0.3% — nothing changed except one flat withdrawal fee being spread across a bigger amount.
So the right question is not “how much do I need to buy for it to be worth it”. It is: does my route have a fixed cost in it, and if so is my amount big enough to absorb it?
Three conclusions#
-
Not withdrawing? A few hundred is perfectly reasonable
You lose a fraction of a percent. “Too small to be worth it” simply does not hold on this route.
-
Withdrawing to your own wallet? Small amounts are genuinely bad value
And withdrawing repeatedly is worse still. The sensible pattern is to accumulate and withdraw once rather than often.
-
Paying about 2% via one-click is not automatically wrong
On a first purchase you are buying fewer steps and fewer ways to make a mistake. Once you have done it once, spot is cheap and straightforward.
Ignore advertised rates. Take how much money left your account in total, divide by how much of the coin you ended up holding, and compare that against the market price at the time. That gap is everything you paid, whatever it was labelled.
