The question is, will users be able to withdraw Bitcoin from these wallets?
I do not see it as wallet, I see it has banks helping their customers to save their bitcoin and other crypto assets that they support. Yes, the customers will be able to withdraw their coins. There have been some banks that are going this. I have a friend in UK (not US) that buy bitcoin this way and have it in the bank some years ago.
Custody services are fine as long as people remember they’re optional, not the whole point of Bitcoin.
You are right, but some people do not have the knowledge about exchanges and noncustodial wallets, this will be an option for such a people if they can not go for ETF.
I prefer the noncustodial way, but this might make some people buy bitcoin.
It basically means that banks will be able to safeguard, control and manage private keys on behalf of customers. Logically, this gives banks the possibility to offer crypto withdrawal as an option to the users but it doesn't mean they'll 100% do it. They still can disable crypto withdrawals if they want.
By the way, since this article says that banks may hold crypto in a custodial capacity, I expect customers to retain ownership of their coins.
I predict that this will slowly spread like a virus and soon lots of states and countries will offer similar service to customers, which means that crypto's market cap will significantly increase.
