Surely a spin up and a larger amount to withdraw would be way more hassle, or am I missing something?
e.g. Spin up to £200. Deposit £10. Wager that (lose it?). Withdraw £200. Seems a relatively low amount of hassle.
Though, not sure why you need to wager a deposit. Surely if they accepted your deposit initially, they should also allow you to withdraw without having to deposit again. That"s their error - not yours. Kinda weird behaviour from them.
