No, because it will be at least 40 cryptocurrencies and BTC in that group.

  That's the state of the world now. Long term, if cryptocurrencies are to be genuinely useful and pervasive, it will probably be exactly one that nails all the design issues and captures 99% of the market.

    I don't think that's true. A cryptocurrency can be optimised, so there'd be currencies for fast and cheap transaction validation (like raiblocks), currencies for more secure transactions (ethereum?), currencies that are strongly private (mimblewimble), and so on. There's likely to be more than one of each 'type' as popularity of a coin will ebb and flow. We'll see lots of them come and go. I don't think Bitcoin is really optimised for anything. It's a brilliant and successful proof of concept, but there are too many flaws compared to other coins for it not to be surpassed. I used to think it could hang on as a base currency that people transfer money between other currencies, but that'd be horribly inefficient and probably unnecessary so I don't think so now. Eventually its price will plateau as people actually start to use cryptocurrencies rather than speculate, and then it'll die. All entirely speculation on my part though, obvs. I don't hold any currencies so it makes no difference to me really.
