until now iam still choose bitcoin
bitcoin without ethreum still work and antoher coin is work and run in marketplaced
ethereum and another coin without bitcoin is colaps
If the bitcoin does not improve and some bitcoin users hack the bitcoin, it will be replaced by the Ethereum.
If there is not further improvement of the user experience, the bitcoin could be replaced by other coins.
i dont think that the price of the bitcoin is going to grow and other crypto currencies will be like other precious metals while bitcoin would be gold
