1) It separates your day to day finances from your betting bankroll
2) It separates your day to day finances from your betting bankroll
3) Money moves in and out of skrill quicker from most bookmakers and casinos than to debit and credit cards
4) Skrill protects you online
Now you might have noticed that the first two points are the same, but there's a good reason for that, and that's that separating your funds has two very distinct benefits. First is that when you start out in this game, you might not have the biggest of floats. You'll want to take advantage of offers as they come along, but your working capital might not cover them all, this can lead you into overstretching your finances and you wind up missing rent or mortgages payments (I've seen it happen, it's not good). What's more, there's always a risk, however smalll, of the bookmakers not paying you or even going bust (Canbet and BetButler are good examples of this). Non payment could leave you in a very difficult situation. So separating your funds means you are limiting yourself to those funds for betting, and it's not going to impact on your day to day existance.
The second reason for separating your funds is the changes to rules regarding mortgage and personal finance lending. Banks and building societies are now much tighter on who they lend to, and will look at your finances with a fine tooth comb. Having multiple deposits and withdrawals to bookmakers and casinos doesn't look to most people like a sound investment, it looks like a problem gambler. Believe me, even if you can proove you're making more than you put in, persuading them it's ok will be very hard. Better to separate your betting and your normal life. It's also easier to see it grow as well!
The third point regarding moving money around is also important, and even more so when you've got a small starting float. Waiting 3-5 days for a payment back to your debit or credit card will mean your bankroll is tied up in transfers instead of making you more money. This is both frustrating and a waste.
The last point is around the added protection from Skrill when making your payments online. Instead of having your debit and credit card details stored at various sites, open to heartblleed potentially, you have one account that you've funded once.
Finally there's all the additional benefits of the VIP programme (which you will achieve pretty rapidly if you get into matched betting and value betting). Cashback, chargeback protection, additional security tokens, foreign currency accounts, a mastercard, the benefits are brilliant and add value to your account that you wouldn't get if you were making the same transactions from your debit or credit card.
