Investors gain exposure to Bitcoin "without the need to buy, hold, and store Bitcoin directly, avoiding the complexity of crypto exchanges and wallets" and lose ownership and control over their very own funds, as a result.
In this way, they gained exposure by getting numbers instead of the real thing. They avoided the complexities of custodial wallets and gained the complexities of traditional financial products.
This is essentially moving backward rather than forward.
We cant actually say it is going backward as there are some pros coming from it. People are investing without the need to know how crypto works. But if you are a smart investor, you would study or inquire how this market works. Because it is like buying an asset blindly, and you have no upper hand if the asset is going down or not.
And maybe, some of these investors would just learn their asset once they already have this currency. Of course, they will be interested in knowing what may happen to their funds.
