I have no bytes but I have tons of blackbytes in my byteball wallet.
I tried to sell my blackbytes in the chatbot but it asks for bytes for fee.
So how can I sell my blackbytes while I have no bytes in my wallet?
You can not sell without bytes

where are your blackbytes from?
WTF? What kind of system uses other coins for fee but not its own coin?
This is so stupid
Maybe you shouldn't have dumped the free bytes for sale then. You're one of the problems. 'Gimmie my free stuff so I can spend it, and then complain that I didn't get more free stuff to dump the other free stuff'.
'What do you mean I can't buy or sell a house without a fee?' - Yes, you need cash to sell a house. You can't use a portion of the house as payment to sell the house. Ok ok, not a great anology, but you get the point.
That's said, go convert $1 of your other alt back into byteball so that you can sell off your blackbytes. And, stop complaining about your free money.
