And who cares? Nobody is accepting raiblocks as a payment. There are more engineers working on Bitcoin and far more infrastructure around Bitcoin. All these altcoins are pump and dump schemes.
Bitcoin has good liquidity and been tested though many drops and spikes. Each time it makes the network more antifragile. No one wants to trust a new currency where a large percent of holders have never been tested and might sell off their entire share at any time.
Bitcoin is pretty much impossible to change now. It's just too big for that.
Example: Segwit voting was available in October 2016 but didn't manage to get significant miner support, finally got activated in August 2017 after a lot of controversy, and is still not seeing convincing adoption[1]. It seems to be stuck around 10%. If a soft fork is that difficult, then more drastic changes must be impossible.
