Is my money insured though Honest Dollar?

Of course there is no insurance against investment market losses however all customer accounts are covered for up to $500,000 in securities and $100,000 in cash via the Securities Investor Protection Corporation SIPC.

Congress created the SIPC but do not financially back it. SIPC is supported and funded by its members, the brokerage companies within it. 

Honest Dollar is not FDIC insured because FDIC is a related to Banking Deposits and Honest Dollar is an Investment Firm.
