I had a conversation with Bilderlings and they told me they don't have any issues with gambling/trading related funds plus they can also issue plastic cards & virtual cards. Spectrocoin does too but I know Bankera is against gambling transactions. Since Spectrocoin is also a sister company - not sure if this can be used long term.
The IBAN Spectrocoin provides cannot really hold funds. Everything transferred to the LT IBAN is automatically transferred to your Spectrocoin account the next day or so.
Regarding Bet365, I stopped betting there to be honest. Below are the bookies I'm currently with (using William Hill the most) and accepted deposit/withdrawal methods:
William Hill: MuchBetter, Skrill, Neteller, Ecopayz, Kalibra/postepay
Paddy Power: Skrill, Neteller, MuchBetter, Paypal
BetFair: Skrill, Neteller
BetWay: Skrill, Ecopayz, Neteller
888sports: Neteller
Betobet: Skrill, Neteller, Astropay, MuchBetter, Jeton Wallet
