I have a feeling that the wide availability of Bitcoin ETFs will herald one of the longest and most stable bull markets for Bitcoin that we have seen to date.
Yeah, sometimes people's assumptions coincidentally comes true.
I've always invested in BTC using a private wallet but with Fidelity's offering I feel fairly safe and confident putting a portion of my 401k into it. I had to check a few boxes that I accept the risk but other than that Fidelity authorized the transaction.
When Bitcoin got developed, it was just in singular, which means Bitcoin alone, nothing like FBTC, Bitcoincash, ETF and some other annoying ones I don't want to mention. If you are investing in something else that is not just Bitcoin, then you are not investing in the real thing, but as long as you are aware of the risk and comfortable with it, there is no problem. I just prefer the real one, which is only Bitcoin. Anything other than that is either centralized or could have very unpredictable results. If it's Bitcoin, there is no way to just easily control the technology because if it were possible, then the government would have done it.
