Basically everything that you have mentioned here does affect the trading. All theses aspects can be studied from the projects detail, and results can be evaluated. Most of the time individual coins price or fluctuations will depend on the projects performance in the market. If they are in line with grater developments then it will call for more investors and if more investors are there then volume increases ultimately. However this is slow and long lasting process where you can not rely on the period but on the larger timelines itself. This is in general idea of it and when you enter the trading market then the real fun starts.
