btc can currently, can be considered the mother of coins, the whole market virtually, depends on this, perhaps in the future, some currency can reach the btc value.
What you say has indeed become a reality and cannot be denied, that bitcoin is a mother and all coins and is always a reference. I have not seen any coins that can replace the existence of bitcoin, although there are many new coins and also very good, but they are still dependent on the existence and movement of the visible bitcoin.
