How often do they do that? Is this activity something usual or unusual? If this is unusual, then I think it's a very bad for Freebitco's customers. I don't understand why people still gamble there, I withdraw all of my funds many months ago when there were unresolved issues for straight 3 months.
When the website was working normally, there was never any occasion where billions of tokens were moved out of the wallet in a short period of time. There was a handful of times where amounts over 100 million were transferred to market maker wallets and Uniswap pools.
After they started having problems is when these really huge transfers started happening. 8 months ago they sent 2 billion FUN to Binance. They received 1.5 billion FUN a few weeks later, but have since transferred another 1 billion tokens to Binance in January and 2.6 billion tokens this past week.
Whether this means that they are close to shutting down, I can’t say for sure. All that can be done is to withdraw any remaining funds from the site in case there are liquidity issues in the near future.
I wish I could withdraw funds... My 2FA doesn't have my country code in it (which I get is my fault... Though years ago I used it without a problem so no idea what happened there), but I've been sending messages to their support since September and no one has replied to the support messages. However, if I make a support request related to the WOF spins not being credited, I'm sure they have a queue set up for it as I get a reply within a week with a macro response.
