I have seen a lot of posts about where to keep your money post MOASS. My idea might surprise you...

Any online casino that operates in the UK has to keep customers account balance separate to their business accounts. This rule came into play in 2016. So even if the casino goes bankrupt, by law you money is safe. I am not sure what each casino would have as a deposit limit but possible of you open up a load of accounts you could safely store money in these accounts until you can get in place a more standard way of keeping those tendies safe!
