Indeed, Ethereum's smart contract capabilities can be viewed as an advantage over Bitcoin in some respects. While Bitcoin's Lightning Network provides a fast and cost-effective way to transact, it does not allow for the execution of complex code logic, which is where Ethereum's smart contracts come into play.

Smart contracts have the potential to facilitate a wide range of activities, from decentralized applications to complex financial instruments, and can enable sophisticated automated decision-making. However, it is important to keep in mind that smart contracts are still a relatively new technology and there are still errors and vulnerabilities that need to be addressed.

Ultimately, the success of any cryptocurrency depends on its acceptance and utility in the wider marketplace, as you rightly point out. While the potential uses of smart contracts may make Ethereum attractive to some, it will ultimately be up to the market to decide whether they prefer Ethereum or Bitcoin.

What I can say is that both Bitcoin and Ethereum have their respective strengths and weaknesses, and only time will tell which one will ultimately succeed in the long run. Nonetheless, I firmly believe that Bitcoin has an early-mover advantage and a more solid foundation, and that its focus on being money is ultimately what makes it most appealing to the wider public.
