well
big mistake .
i have more than 10 big mistake, the only i remember when i buy about 500k TRX with 3,2 eth on etherdelta.
then i sell too fucking fast , actually i can get x10 or 20 or x30
but i am too hurry to take x2 profit.
you still get a profit, it's very unfortunate but this often happens. this teaches us to stay patient but also not too greedy.
