How to fund Coinexx?

So I am totally new, first time trying to fund a live account and just opened a new live account at Coinexx. I want to fund my live account with USDC crypto. So I opened another account at Kraken to buy USDC with my linked bank account and then send crypto to Coinexx.

Now Kraken says that I can withdraw after 7 days!!! Isn’t it too long?

Is there a faster way or better method to buy crypto and withdraw?
