If I am here it is because I belive in this coin, otherwise I would be on Bitcoin or on some other coins, on the other hand I am not dreaming: taking down Bitcoin or only being ahead of Bitcoin is no simple mission: it's the only crypto that is (a little bit) known from general public, it has the best tools/support from community, it has the biggest market cap, the biggest dev community, etc.
Still there's room for other coins : we can be one of them and there's still room for improvement; we can also bring those improvments
