The reasoning is (I'm not saying I believe this will happen just that it is an interesting thought experiment) that if people quit the shady exchanges and start trading Bitcoin ETF in substantial numbers it could begin to starve the crypto network of transaction fees and the exchanges and other crypto companies of customers.
If Bitcoin ETFs become the main way bitcoin is traded then purchasing bitcoin is just for speculation and not an 'investment in crypto and the future of finance', in that case it's much easier for the bubble to burst.
About 70% of the S&P 500 stocks are held by mutual funds or ETFs rather than individually held.
If you trade stocks and would like to buy bitcoin (as an investment) are you going to do it with an ETF through your broker where the money is protected fairly well by law and insurance, or manually and make sure you don't loose it, or through an unregulated crypto exchange?
Use of Bitcoin as a currency (for buying things) has dropped from 57% in 2019 to 32% in 2023, the rest is speculation and inter exchange transfers
I get your point but without bitcoin being an actual real thing the whole ETF thing won't last either.
"Nobody Goes There Anymore, It’s Too Crowded"
but what about cash you might ask? cash has always been used for everything of course both good and bad but transporting millions of some fiat currency in a briefcase is a lot harder than stealing some wallet with monkey jpegs or tokens worth 45k usd.
the fiat system of currencies has worked and could work but wholehearted replacement of them is akin to just throwing up one's hands and not vying to fix the underlying problem. doing so would do far more good than just making it easier to pay someone but would mean an overall more stable government for the people long term.
Yes, this is just so easy to do in war torn dictatorship! Just get your often undemocratically elected government that has never done anything for you to change everything about itself!
But more likely, people in our generations will still be working until they are 70+, and their 401k will have some allocation to a Bitcoin ETF.
