Bitcoin is the mother of Altcoin, perhaps that is a suitable word to describe Bitcoin's current position. After Segwit I hope its position can not be replaced with BTC split. As has happened to ETH split into ETC. Worth the wait for Bitcoin's future.
As we all know altcoin was made because many wants to follow the success of bitcoin and wondering if they will succeed too. Some altcoin copied or made platforms that are not far to bitcoin. As bitcoin is the top crypto currency and it will ever be. Nothing can change that even decades will pass.
