you say it instead(your first sentence), many think that there would be an altcoin in the future that will be better than bitcoin, i say this is a blatant bullshit, not gonna happen, nothing can be comparable to the huge network of bitcoin, every new coin would just be a bad joke in comparison
and no coin can just be created and surpass bitcoin overnight, it will need so much time for any new coin, to even start to think to overcome 10% of what bitcoin really is, and meanwhile bitcoin will be already on the moon with even more of a huge network
Many companies and technologies are thing of the past now and no one foresaw it before it was too late for example: Nokia, Yahoo. Bitcoin might be big right now but it doesn't mean it is a clear victor.
We need that killer apps and services!
