For all the Havelock folks - realize that you run the same risks as the guys who kept BTC at MtGox:
It is not wise to keep shares there (or BTC): Use exchanges to buy or sell, not store.
This is exactly why I was asking. If my regular stock broker goes down, I don't lost my shares. But if Havelock goes down and my shares are not registered anywhere else, I lose control of them?
Issuer of the shares is receiving daily (or even more often) the list of usernames with the number of shares. Ofc, you have to trust the issuer.
We went through the closing of several exchanges, and we still have our shares.
