I don't day-trade, I put some amounts in coins I believe in and leave it there long term but lately the alt market is craaaazy so I was tempted and gave into some smaller trades. Now indeed I am facing the same dilemma. Should I close last week's bought AMP at 110-120% or still hodl for more? It already went down from 150% ROI yesterday.
Got some Pascals the other day: 65%+.
Should I hodl on the NXT which is said to boom towards Q3? Should I keep the ARDR that were dropped on me from the NXT or sell them now?
Decisions, decisions... See why I don't like day-trading? :)
All I can suggest is that Nobody has ever lost money from taking profits. But if you are in it for the long haul there is no point in watching the markets. You should believe in your own judgment of your investment.
