I Won On An Online Casino And Need Some Advice.

I won 60K on one of those stupid sweepstakes casinos. They seem a bit scummy but from everything I’ve read they do pay out.

The concern is there are 2 options to withdraw funds:

1 - Bank transfer. I went through the steps to connect my account, but it doesn’t reflect this on their site. Chase however does show the link. Their customer service has been unresponsive for more than a day.

2 - Debit card. They can transfer the money via debit, but there is a 10K limit. If I initiated 6 withdrawals for 10K each it would certainly look like structuring to my bank.

What do? I’m getting a little antsy with their lack of communication and I’d like to get my funds withdrawn as quickly as possible. What risks are there if I go the debit card route even though the intent is not to structure for tax avoidance purposes? Do I need to communicate with my bank prior?
