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.

sad right ?

Have you checked the recent prices of TRX? The current exchange rate is around 1TRX = $0.04, which is less than the price for which you sold your coins. So you don't need to be disappointed. You did the right thing. If you still don't feel good, then you can go ahead and purchase some of those coins at the current levels.
