Intense Onlooker.
So in your words you "Just topped up at 13c and 12.5c, sincere gratitude to those selling at these prices"
Ok so at the present 12c price you are down 3.84 % on the 12.5c purchases to 7.69% on the 13c purchase in one day and those that sold to you have saved themselves this loss.
Strange logic.
Good luck with that one.
