I have to say I am really worried about this entire economy. It s true that we re still in the early stages of development of meaningfull crypto securities markets but NOTHING. I guess it s in human nature to scam if allowed to do so.
If you look at most hashing organizations, and then look at historical difficulty, growth of bitcoin and the like it SHOULD be pretty apparent to people that if you want a solid investment (Not one for churn and burn) then there really aren't any mining companies out there that has a sustainable business, because mining in of itself isn't overly sustainable in a long term way unless you have severe capital and hardware infrastructure. Usually if you have those two you don't have to rely on internet investors in exchanges.
I certainly wouldn't say that all businesses are in violation of the SEC rules, believe it or not, some companies on the market do retain legal advisory and they've indicated that deals CAN be structured legally to accept investment.
SEC's A+ system is by far one of the best things to happen to crowdfunding in the US. The requirements are absolutely fantastic, and terms are great to small businesses who are starting up. Granted, out of all the businesses on HL, cryptostocks and the like, very few will be able to meet the requirements (We will be one of the few that is eligible and will go for A+ as soon as the SEC rules are finalized in 60 days).
Additionally, it hasn't helped the bitcoin ecosystem that most investors as well as issuers want to retain as much anonymity as possible. A honest question that people need to ask is how many issuers can you think of could be reached by phone or physical mail during the startup and issuing phases of business? I can't think of many, almost all of them were email addresses, and websites and nothing more. Sure some had names, but most people successfully faded into the background once their scam was complete, or the business faltered.
With A+ there's certainly going to be more investor protections, but people will need to realize that the average startup failure is in the 60% range already, and with new tech it's even higher. Rewards are certainly high, but i can't think of any bitcoin-specific entities that have done quite well, granted a few are still establishing themselves and haven't collapsed yet.
