It will evolve (Bitcoin will have smart contracts), this is the whole point from making it open source and by your logic, Ethereum will be useless too, and so is anything else each time a coin with a more advanced blockchain techonlogy is released.

Bitcoin needs to solve its transaction issues to have any chance at staying relevant in any of the future Blockchain versions. With blockchain projects like NEM doing about 4000 transactions per second, I wonder how bitcoin's 7 transactions per second will compete against that.

The point is that Bitcoin will improve, which is what MadGamer said, and I agree with that. In case it didn't improve (which is purely meant to be an example), MadGamer again rightly said that Ethereum and all other coins would become useless too by that logic. Don't take someone's post out of context, there is no need for that - read and acknowledge. Bitcoin has the first mover advantage, the most money circulating in its ecosystem, and the most secure and stable network. And don't look at market caps to think that Bitcoin is being surpassed by altcoins - market cap is a noob metric. Altcoins have their insane total supply to artificially boost their market cap. To add; Ripple and a few other altcoins have already surpassed Bitcoin's market cap, and that more than once.
