At 1st set "Auto Exchange" to BTC.
At present time don't have enough for withdrawal.
Now changed to "Auto Exchange" to LTC.
Too soon to see any LTC.
Question - those BTC that have already been "Auto Exchanged", can they be "Auto Exchanged" to LTC? Or do I need to let the BTC balance get large enough to make a withdrawal? I.e. so that the 0.0003 BTC fee isn't the same as my balance?
I have the same problem!
Admins, add please Auto exchange from Bitcoin

It must be a very small amount that's hardly worth withdrawing; why not just leave it as BTC until you have enough?
You were the one that set it to BTC to begin with and you can also change to LTC another time.
There is no internal exchange and no Bitcoins are being mined so the pool would have to transfer the small amount all the way to an exchange.
