well mostly ICO do that, i say mostly since not all ICO was a scam. and keep their words to bounty participant and investor.
I don't know if you guys felt the same way like I do towards s***ty ICOs! Therefore, I can say that ICOs are a thing in the past. I would root for STOs this time, because they're regulated.
When you file paperwork with any authority, you are removing your decentralization. The authority has control over everything you doas an individual. It has to be done in line with the laws and rules of that country.
This means that, as well as passing over all of your information, you are also allowing the governing body to get information on all of your participants, whom will then be subject to taxes, laws, rules and controls of that country. It kind of removes the spirit of true decentralization, doesnt it?
