Also read Andreas Antonopolous' comment because it also applies on wbtc.
In any case, wbtc is nothing but a new token issued by Bitgo for users to trade in Ethereum based decentralized exchanges while your bitcoins are in Bitgo's custody that requires KYC. I shake my head hehehe.
When the term Bitcoin ETF is mentioned in the crypto community, it is likely accompanied with a positive response precisely because of its tendency to skyrocket the token to a larger platform for investment, thus birthing bigger returns.
However, a cryptocurrency investor has expressed his concern for what might become of Bitcoin if the SEC agrees with the Bitcoin ETF applications. Certain that the token will lose its value, the user under the pseudonym “mariner2525” cried out via Reddit saying
"Bitcoin ETF is the worst thing that could ever happen to crypto. They’ve been rigging gold and silver – they will totally rig Bitcoin price by diluting it with derivatives.
After ETF- and a temporary spike in price – Bitcoin will be dead low all the time”
Antonopoulos explained that Bitcoin ETFs are aimed at making Bitcoin a tradable instrument suited for the stock market, which places it under the supervision and control of a custodian who holds the actual Bitcoin while investors are left with a share in their funds and not the Bitcoin itself.
In his words
“ETFs fundamentally violates the underlying principle of peer-to-peer money, where each user is not operating through a custodian but has direct control of their money because they have direct control of their keys”

I absolutely agree. With ETFs, it's not going to really benefit day to day bitcoin users at all. The thing is that these ETFs are attempting to target whale investors as well as institutions who want to invest in bitcoin, without having to hold bitcoin themselves.
The fact that someone who is investing in an ETF is not able to hold any bitcoins, or anything that is backed by bitcoin sounds like an extremely dangerous idea. It can obviously start manipulation of the market as well even though I do think that's less of a concern with bitcoin as you mentioned due to the more liquid nature of actual bitcoins, compared to chunky gold/silver pieces that needs to be melted into bars.
But all of this means that ETFs shouldn't be hyped up like it is being right now. It defeats the purpose of a decentralized crypto in the first place, as a store of value. With the wbtc created by Bitgo, it defeats the purpose of a decentralized exchange as the funds need to go through a centralized checkpoint before it can be converted from BTC to wBTC. Both of these instruments aren't something that I personally would appreciate or use at any stage, even if ETFs do get approved.
