For a Coin to be best , many things matters for us because only single factor can not make a thing Better.
Here in my opinion that coin is better which has honest owner first , Because this is the owner than didn't thought much about to make money but he also thinks about the coin's holder to make profit .
Second thing should be the better team work , means to say that they remain active in the cryptocurrency field to give the coin active quality in the market according to demand , so that coin doens't go toward the dead coin .
In this way coin may be said to be perfect and can give much profit to the people   without pumping or dumping .
