If you look for a “custodian” for your money, you might use a Bank. And, that Bank may also offer you services like lines of credit, overdraft protection, loans, etc.
If you have Stocks, you would use a Brokerage Firm, and get services like loans against assets, or borrow against margin.
For your Crypto? Not many good solutions yet.
