FAQ
Is fiat buy the fastest beginner path?
For many users yes, but only after checking payment support, limits and the full quote structure.
Why does the price on the page keep changing?
Quotes can move with market price, payment method, liquidity and refresh timing, so different entries may show different numbers.
What should I do after the purchase?
Check where the asset landed, whether it should move into spot, and then decide on trading, holding or transfer.
