I purchased BTCD @0.0085 i thought its a good point after 0.05 reversal, but i was wrong, its even more down, i have a loss of around 1.3 btc i put in 5 BTC kindly give me your valuable feedback what should i do , i am a student, i have lost alot in past, but not sure why i allways loose

.00085 is not a bad price if KMD takes off.
And my best advice for trading in general is cut your losers quickly. I am not great at this myself, but getting better.
But I definitely wouldn't sell BTCD at the current price below .0007. That would be dumb. If KMD rises, BTCD will rise and there is a big blockchain conference next week where KMD developers are presenting, so price could easily rise for that.
