That's not true for one gold heroes U sell one two star 1 gold hero u get 3 gold and u bought them for three as well. U sell one two star 2 gold hero u get 5 gold and u spent 6(2+2+2) to get it. U can see he is only buying and selling Akai miya Angela alpha chou and all as they all cost just one gold. He is also not doing it for nothing. The commander he is using gains a shard when u level up any hero to higher star and if u get 7 of them ig u get a mirror device used for cloning any hero u want
