As the question reads. For me:
- The concept/vision - is it innovative? does it solve a real world problem? is the problem it solves something I am interested in?
- The team - Size and experience.
- How the coin relates to the concept. Is the coin a key part of the platform? Are other payment methods available to users, etc.
Here the first factor for me , always forces me to see the what the unique quality or concept is with the coin that is making it much better and unique from another coin .
Beside of this quality for me the better thing to analyse is numbers of the units of the coin that will be specify by the team before the launching .
Here no. Of coins really tell about the price of the coin , Because here if the no. Of units of the coin will be less then the price will be high performance coin and that will create a big difference in buy and sell price of the coin , and in that case we will be able to make small small amounts of bitcoin to that coin trading to make profit .
Another thing that I see usually is the background of the business of the coin's owner Because background is a big thing for the coin's future , if the owner of the coin's is rich person and also famous then we can expect better results from the investment in that coin .
