If you did, Bitshare founder's Daniel Larimer's comments at the bottom provide a couple more

Namely (i) As he points out governments tend to like to be involved in investment and money transmission schemes... and the likelihood of the SEC taking a dim view of the trade and marketing of unregulated "shares" is probably a tad higher than the likelihood of your USD deposit account being frozen or haircut. (ii) he appears to imply the only thing that went wrong with MtGox and "other otherwise trustworthy institutions" is government intervention. Whether that selective blindness to MtGox's problems was purely rhetorical or not, it's a remarkable attitude coming from the founder of a crypto exchange...

Of course not, if you think it's likely don't put your money in. Even Bitcoin's rapid price drops in the past have not been fast enough to have triggered a peg break. And you're trading the risk off against the risk of a bank haircut or account freezes or what have you.

Again, to be clear: I am not encouraging anyone to put their money into this.
