How big of a transaction can I make on my debit card?

Excuse me, I have a question about the limitations on debit card transactions when it comes to cryptocurrency. I'm curious to know, what is the maximum size of a transaction I can make using my debit card on your platform? Is there a specific cap or limit that I should be aware of? Additionally, are there any fees associated with making larger transactions using my debit card? It would be great if you could clarify these points for me. Thank you for your assistance.
