My 2 cents:
Bitcoin is like a Toyota. Limited functionality, battle tested, robust and high reliability.
Ethereum and others that support native smart contracts are like a Tesla. Cutting edge technology, but sometimes things don’t work as they should.
For example, take a look at how many hacks we had in the last 4 days. It’s not Ethereum’s fault, but it’s still on their network. So, I think the original concern around bitcoin should actually worry Ethereum and other Native Smart Contract chains.
I’ll end this post with this quote:
Ethereum has vast potential, whereas Bitcoin won't ever do anything well beyond implementing a currency.
