I understand that logic. But it doesn't change my mind when I bought at 45 and sold at 82 It seems I should have almost doubled instead of dropping by 50%. I will try it as you say.
My previous post was wrong, but I guess I don't understand the numbers you are giving. It looks to me like you bought STA when the price was 0.000083 BTC (0.0113 / 136.8 ) and sold STA when the price was 0.000040 BTC (0.0054 / 136.8 ).
