I think you need to get your E-Wallet and Bank in sync immediately. Storing your money in your E-Wallet is bad, you should only use your E-Wallet to transfer funds if you can. It's the same thing for keeping your entire bank roll on a skin, that skin is investing your bank roll into a sweep account and earning interest off of it while you're no wiser. They aren't delaying your withdraw request because of processing, they're delaying your withdraw request in order to accrue the interest and transfer the money back from their sweep account into your account. You need to find a way to earn interest on your bank roll, even if its just the interest from your bank, or find some way to move your money between your sweep account, your bank, your E-Wallet and your skin where your interest > rake.

It's not a huge mistake at micro levels, 1,000 dollars would earn 10 dollars a year at your bank etc., but when professional poker players tell me they keep 100,000 in cash in the casino lock box, it makes me want to vomit. I don't do short term investing and I'm not familiar with the rake from the E-Wallets, but I'm dead certain if you're not earning interest on your bank roll you're losing money. The returns may be too marginal to justify the hassle, but even still, just leaving your money in the hands of skins and E-Wallets is leaking $, and it could add up over time.
