It would be a very good idea, provided they don't already. I haven't checked for quite awhile. The problem, of course, is that it opens them up to attacks involving mass withdrawals. Easy, effective solution would be to increase the minimum withdrawal amount, but that has its own issues.It's not as simple as just sacrificing 5 cents per withdrawal to make sure customers get their coins within 24 hours. Don't misunderstand me, I think it's ludicrous not to pay a fee. But I'm saying it's not as easy as flipping a switch -- there are other concerns.
