I hope so too but from what I'm observing altcoins are just there to stop Bitcoin all this time. Back in 2018 Bitcoin's dominance fell as low as 35% and the chart speaks for itself. It seems that all these nonsense are not going away easily.
Never said they were going to go away easily. It's most likely going to be a long and painful process, and will consists of a lot more new altcoins.
We have DeFi now and some influencers are calling holders to sell and wrap their Bitcoins in ERC20 tokens to profit from lending (which contains hidden risks of illiquidity and possible withdrawal problems). Altcoins already own a big part of the market and increasing it.
We've had this "DeFi" thing for years already, "DeFi" is just a new sort of "cool moniker" for Ethereum apps/projects to make it sound "cool".
