That's true, a good trader is an experience trader.  A good traders really knows of when is the right time to sell their cryptocoins. Im not going to sell my coins at a lower price, if ever it will increase X5 at my capital that's my mininum price that i will consider to sell my cryptocoins. I also invest at ethereum, litecoin and ripple they are the best of all altcoins and im not going to sell them now because i really believe that the rise of cryptocoins at market is not yet over and it will continue to rise until at year ends.
