Financially supported? Not at all.
Not a dime purchased or sold on the open market, through ETrade/Scottrade/Fidelity/etc. has directly funded Baltia.
Private Placement shares are what funds Baltia's operations.
Full Clarification:
Example 1: You have $10,000. You deposit that $10,000 into an online brokerage account. You purchase shares of BLTA through your brokerage website. You now have $10,000 worth of shares. That $10,000, minus the transaction fees, all goes to the person who sold those shares. Baltia doesn't get a dime of that.
Example 2: You have $10,000. You call Baltia Investor Relations. They say they will give you "x" amount of shares for your $10,000. You agree. You write a check or wire $10,000 to Baltia. Baltia now has $10,000 to use towards it's certification process. You get your shares in a certificate form with your name on it and must hold for a minimum of 6 months.
If you personally never bought private placement from Baltia, you have not financially supported Baltia's certification endeavor whatsoever.
