You are not alone Col...
I withdraw most of mine, regardless of source and leave "pennies" in the bank, my paypal and my Skrill.
Various reasons which include
I am very old school and prefer to deal in cash
It is part of my 'staying in control' in relation to gambling, if its not there I cannot exceed budget and CBA to go out for PaysafeCard, worked well for years lol!
Part conspiracy theorist so no one can check how much I have or don't have or rob me online
When I have a big win, I like to look at the 'wedge' rather than just numbers on a screen
Only real difference is I don't have the thousands under my mattress
