Bitcoin is dead. Long live Bitcoin

I was going to post this in r/bitcoin but to be honest, that sub is borderline moronic so I thought I'd actually post it here.

I want to engage in a discussion about BTC vs. alts... more importantly, what makes BTC actually reign supreme and if it will stay that way later on as adoption grows.

What, other than being first to market, makes BTC the best option for crypto investments?

We speak of Bitcoin being able to bypass government rules, monetary policies, controls. We also talk about how Bitcoin will change and revolutionize finance and business. What I want to know from you is HOW do you envision that?

One thing that Bitcoin is lacking severely is the ability to do smart contracts. You might not believe that this is an important aspect of crypto... but it is, in fact, a crucial aspect of financial transactions... IF we are to deal with "big banking". Without smart contracts, there are no loans... without smart contracts there are no quid-pro-quo transactions that insure the goods/services are provided for the payment issued.

So based on that, how do you see the big dog staying that way... does it stay a "digital gold" that it has been turned into by Michael Saylor? Does it become a novelty? Still very valuable but instead of being a form of payment it is more of art, it is the "Cool thing to own". I, personally don't mind this so long as it's worth few hundred grand a coin... LOL... If this is the case, then other networks, such as ADA or DOT, would have to take over as the foundations of the DeFi system.

Or does BTC evolve in the next development cycle to incorporate smart contracts, and ultimately grow into a "swiss army knife" of crypto where it can just do it all?
