The idea is good. It is more secure for investment. Countries can issue coins and trade. Actually, it already exists. Some countries issue coins and customers even get the benefit. The thing is that the benefits are not so big compared to other cryptocurrencies. With the bitcoin for example, in 20 years, we are going to have many millionaires. We even have some millionaires this year thanks to the cryptocurrencies. Governments cannot allow that. The benefits will go straight to them. It is like the banking system. Actually, banks make a lot of money for people. The benefits go to the banks and the countries. People who invest in banks get something. The biggest part of the benefits goes back to banks and countries. In that case, I will not invest in a coin issued by a government.
