As we know that blockchain is a good kind of digital technology, it is always possible that there are many business, corporations and many more countries are supporting for this blockchain technology, for the find this technology very useful for the improvement of the different business strategy.
in cryptocurrency, there are indeed many companies that make their own coins. so that a project emerges. with more and more countries supporting it, more and more projects will emerge and develop their own coins
There are a lot of developers that wants to present their coins but they are not companies.
There are some groups or sites that release their own cryptocurrencies, and I think they already have a project to start with in their release of that certain crypto. Also, countries don't support their coins or cryptos or project, they have their own investors and that is the reason ICOs are being made by them. Without investors, that project will obviously end quickly.
