The real truth of the matter is that most of these major altcoins aren't even bringing anything new to the table, they look at bitcoin and say "we can do all of that BUT BETTER" and come up with some mediocre use case (most of which don't even need blockchain or decentralization) and 200bil coins not backed by any proof model and sell them to people who think they're going to get Lamborghinis.
They think they can be Bitcoin 2.0, but in reality, bitcoin is the only one that's been in the fire long enough to have developed real resiliency, and what these crapcoins don't understand is that they will, one day, run into the same scalability issues, that bitcoin is already 2 steps ahead on and actively working to fix.
Privacy, smart contracts, viable scaling... all of these are things that bitcoin will eventually be able to do and then everyone else is left wondering what the point in using those other currencies is. Sure, right now, the fees are inconvenient and the transaction time is slow and that's frustrating and annoying, but if anything, the bottle neck drives up price volatility and makes it an even more attractive speculative asset.
Half of this speculative cash being tossed around wouldn't even exist if it weren't for bitcoins battle scars.
