We all know that more than one country imposes an ICO ban. Because of these prohibitions, direct participation of people living in certain countries to the ICO is prevented.

Well, does this really fit the specifications of the market? Dozens of ICOs that mention that they are decentralized do not collect investments from these countries and comply with the prohibition. But wouldn't it be that the right center is centered and the ICO is involved?

I think that the prohibition of participation in the market has caused great damage. OK, the right ICOs should be supervised and the people who invest in it should not be harmed. However, the project claiming to be decentralized, the ban does not come right to start with! The principle of being decentralized is undermined.

Accepting participation from such regions might not be the problem but maybe the law or the government totally prohibit them from having any dealings therein.

I think any small country is a trego of the world. Simplifies laws and allows ICO registration. To become a market leader and get a big financial flow to your country.

I agree with your point such restrictions and other requirements like kyc is also against the decentralization concept and also the basic concept of universal currency and borderless use cases but at the same time these requirements are set to follow govt and regulators guidelines to remain compliant by the icos.

more than year I learn cryptocurrency and I see that many things are not decentralised, you see that if btc falling - 90 % of currency is falling too..thats funny

Unfortunately the real decentralized currency is not needed by the states.  The manic passion for control will leave this world with the last person
