"if this coin can survive so long time"

How can a coin which has a full team of skilled people working on it die? price and volume can get lower, but the product is coming, so there is no way it can die!
Besides, Verge was just hacked and it was a mess. That coin has huge volume and market cap, but it went into real trouble, how can you explain this? Easy: you can pump a coin with no project and no skills behind it, and you can have a great projects with low volume. There is almost no relation with the technical value of the coin in most cases. Not now in history, at least.
