The EU was planed to create a stock exchange that is regulated and decentralized, and USA has started publicly that bitcoin and other two mediums that have most highly valued presence in the cryptocurrency. And so many ICOs are implied that who work to increase the value of security.
For example one person will buy stock in a company and gain some percentage percentage of that company and person buy tokens in ico and he owns a % of start up. and cryptocurrency can not trade 24 h online. All are bought and sold by stock exchanges, which are open only fixed hours.
All government agencies like SEC and exchange board of india regulated ICO.
In the SEC maintains no one can seller in the marketing of the asset. and the person who have been highly decentralized more are less since their inception. all people are get idea to allowing parallel currencies though govt have alternately lac and Draconian while more or less their inception.
As for perfect review the cryptocurrency is a really bubble and we can not say when it blow and when it blast. its perfect thing to in vest maximum more hope coins. we dont want to invest only one coin with all of use money if the blockchain can be used to any thing so password will very strong. and we want to remember 100% because some blockchain wallet has not password recovery. Use social media to know about latest and trending news. But do your own survey as much as possible because of its money and your risk. if you do more hard work is more success...
Finally i say that knowledge is divine. If you share how much of knowledge you will gain more.
