I don't trade coins though but I assume its less risky to stick to the coins that are already on top and has been traded regularly.
The great thing with yobit is that you can get free new coins to test its waters.
True, that is a correct idea. I also feel more secure to trade on coins that is already on top than with the new one. I need to see how the new coin has been working before i decide if i will invest with it or not.
