Basically, many, maybe even most of the so-called securities here are not compliant with US SEC law.
That doesn't mean you cannot buy them, but if they get taken out by the SEC, you will simply be waiting in line like everyone else for your now meager piece of the pie.
The unwritten history of bitcoin securities markets is that there have been three or more that have been purposely taken out by government action. Some who saw the writing on the wall for what it was may have profited. I believe most lost at least some money in whatever form.
There was even one that lasted a little longer by not allowing US investors to buy shares, BitFunder. However, it seems that other problems plague them now, probably due to lack of liquidity. US investors represent something like 90% of funding. Take that away and...
There are some advertising restrictions on "unlisted" securities that mean that a company is not allowed to use public media to acquire investors. That means advertising shares for sale on something public like bitcointalk will mean non-compliance.
