€50K on the payoneer, is it safe?

Hey, guys,
I'm at 50K EUR on Payoneer. Should I worry about transferring this money to a bank or can I keep the money there?

I've been using Payoneer for two years, I've never had any problems. But I would like to know if I can trust Payoneer for large amounts.

If I have to transfer the $, who would be the best bank to send this money?

Thank you for your feedback
