What’s the fastest way to buy crypto with a credit card?

I am finally ready to jump on this current market correction, but my main exchange is taking forever to clear my bank deposit. My goal is to find a platform that lets me buy crypto with credit card instantly so I don't miss the entry point. I am also looking for a reliable exit strategy for later because I want to be able to Convert BTC to cash Paybis style without waiting for days.

And here is what interests me:

- Has anyone recently managed to buy crypto with credit card in under five minutes?

- How smooth is the process to Convert BTC to cash Paybis when you need the money back in your bank?

- Are there any specific cards that usually get declined on these fast-exchange sites?

- Which platforms offer the highest limits for instant credit card purchases?
