taget taking profits must set before we open transaction. Alot traders didnt set it till finally profits becone loss again due market direction changed. Greedy be main problem from each traders, they want more profit and prefer instant result. Most of them didnt trust the progress. 5-10% was good result for each trades, as long as we could consistent i am believe our account will growth.
For short-term trading we should aim to take profit for the highest 10-20%, if we don't determine profit then we will lose the moment to sell at the highest price because price speculation can rise higher, but the impact of our greed will fail to take profit at high prices and instead lose money because the price of altcoins is unpredictable.
For the short term even the 10-20% margin is quite high according to me. Just a small variation is enough to book the profit.
