hi, in my opinion what can make Ethereum and similar projects survive is its smart contract system that can be used by new projects to make their own coin (sorry if I'm wrong), but if one day Bitcoin makes a smart contract system too and can be used by other projects to make their own coin such as smart contract on Ethereum system, then will Ethereum and similar projects survive? because as we know Bitcoin is very popular and many people invest in Bitcoin (BTC Dominance in cryptocurrency market is 66%), so surely new projects prefer to use smart contract from Bitcoin and it makes smart contract on Ethereum and similar projects less likely to be used (few will use them), so will that have a negative impact on Ethereum and similar projects?
*Note : I apologize if my opinion is wrong,
thanks.
Ethereum is the king of smart contracts and if you see the statistics it is the most used and popular smart contracts network so i think even if they are available on btc still ethereum will remain number one as there are dozens of factors involved that decide the choice.
