It may be a none issue for those who are investing. That's not me. I'm not investing. I'm not holding on to any crypto currency, I'm cashing out at first opportunity. When cash flowing like this the direct immediate costs are most important because I'm not choosing when to sell. Whenever payout happens to my wallet within a day at most I've already sold for cash. Cash is then available to use to when I find a good deal on a GPU(s). As more GPU's are added I can expand faster and faster. There will be a time when I decide to stop expanding and only at that point will the issue be relatively low importance.
Then it's a none issue. Send it to the exchange yourself or let the pool do it. You're most likely using the same exchanges.
I'm sure most people convert everything to bitcoin as it's the easiest to convert to cash. You can literally send it to a Bitcoin card, withdraw from one cash machine, deposit into your current account and is all available within an hour then go live the dream and stop worrying.
