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. 

Who would be a better custodian for Crypto deposits?  Banks or Brokerage Firms?  The BullsEye Guy Shortcast https://bit.ly/3ae2TZV
