Though, it would seem to me that Freebitcoin was never supposed to be wallet, in the first place. Sure, they offered some tools and instrument for people to win passive income through deposits of Bitcoin and also in their token, but to me it was an over kill from them.
They were already profitable and a casino, why would they even bother to turn into a neobanl as well?
I still believe their FUN token was the main cause of this disaster to unfold, it could provoke some imbalance in their liquidity, forcing them to withhold money from their gamblers and depositors in order not to go bankrupt..
For you and me it wasn't supposed be a wallet, but for many people it was. IIRC they even communicated about it here.
Why they needed it? Simply to have more BTC in their hot wallets for ongoing operations.
Lot of speculations and unknown factors about current situation. But things not goingas planned with FUN indeed might be one of main reasons
