There is no option to control the satoshi/byte in there.
Robert just told me I could change it when sending money to my card.
Where is that option?
Hi Dangerous_Mind,
When topping up your card on our web app, a wallet address will be created for you to send us the BTC amount. You can copy paste the BTC address into any BTC wallet and choose the satoshi/byte. Your card will be topped up as soon as we receive the amount. This can influence the time it takes until the funds are on your card.
Best regards,
