Bitcoin is the master for all crypto currencies, so i strongly say its reputation is based on we users of bitcoin and in banking sector bitcoin took a leading place as bankers competitor.
other crypto currencies are like earth worms before this big bitcoin snake those earthworms may be fallen like stars but not the bitcoin.
The world is famous about crypto currency and the master of crypto currency is Bitcoin and this will be the future reason behind the plenty of votes and usage of bitcoin is high day by day
If such replacement happens the trust on crypto currency itself breaks to my estimation.
That's right, if bitcoin will be replaced by another one, this will be the end of the whole crypto story. Becaue the bitcoin is the base of the sector. Bitcoin is not only a "COIN", it's the most significant part of blockchain and its technology provides great opportunities to us. I don't think it will be surpassed by another coin.
