Most withdrawals are processed instantly, at least as per my own experiences. I never experienced such long waiting for my withdrawal at Coinroyale so far so there must be a specific reason why his withdrawal took over 40h before it was processed.
You are an experienced gambler so you did join CoinRoyale for too long. Did your forget your first withdrawal on CoinRoyale and how long did it take?
My first withdrawal in Coinroyale was few years back so I cant remember how long it was processed, as long as I remember I never experienced such long waiting for my withdrawal in Coinroyale. Probably because most my withdrawal amount were small amount, worth few hundred dollars only as the biggest one.
