I believe in Bitcoin. This is the most important coin and not one altcoin can not overtake it. I think there is no altcoin that can surpass the greatness of bitcoin because it is the undisputed king of all the coins. Bitcoin Cash is an interesting project, But I do not have confidence in it.
There is no better project than bitcoin. Yet he is far above all. We can see good projects, promising and better than bitcoin. But still, these coins are only good in the interim, and bitcoin is good all the time of its existence.
