I understand Bitcoin is a convenience but I think several posters here move coins around too many times a week. I balance everything out maybe once a month. Not worth the hassle waiting for that Bitcoin to hit from your book to your wallet... and then moving it again on a weekly basis.
Bitcoin fluctuates way too much. Not worth the risk.
Most I ever made from a book to my wallet.... because fluctuation was in my favor... was around $102.00 (I know... crazy lucky)
Most I ever lost from a book to my wallet because fluctuation wasn't in my favor... around $48.50
Like I said... don't get banged. Don't get caught in a jam. It will happen eventually.
