Tell me about your trading strategy.
How much coins do you use when you trade? All of them?
How much time is it appropriate to hold a coin?
Thx
I don't suggest that you trade with all of your coins. It's best to hold a portion for a long term investment. I suggest holding 50% or more and trading the rest. One of the main reasons for this is that you can't fully trust exchanges. They could get hacked or just steal your money. It's happened before with MtGox, Cryptsy, and others. Also with trading you have potential to make more profit but you could also lose out on big gains if you sell and the price keeps going up. So there's no guarantee that you will make money trading.
Holding 50% of all your coins is a good idea and you have the good chance of experiencing good profit for the future. Selling at earlier time isn't a wise decisions, because the price still at lower value which actually can make your funds not growing as an investments. The trading strategy might be so challenging by the time trading it directly and sell it in the right value at an specific time frame.
