First, select one or more of the highly usable cryptocurrency types, followed by a common convention of all countries for that currency, and, most importantly, soliciting citizens to agree.

The cryptocurrency market is booming and fast. There are many investment opportunities and I always want to invest in this market. This is a promising future.

The growth of bitcoin and Altcoin has shown a tremendous amount of power that will change the way in which the world's big corporations and governments can not anticipate.
Bitcoin is the bubble, but also the future.

The real value of Bitcoin is not reflected in the price. It lies in usefulness, convenience. It's also where you want to get Bitcoins. No organization can intervene and control. So the real value should be reflected in the security in the purchase and payment.

In Vietnam, for example, most government budgets are from people's taxes. If people invest in electronic money, the government will not be able to collect taxes, the government is only interested in money. The less taxes they earn from people, they will not accept it

Cryptocurrency can be very profitable but it is also very risky, the stock market seems to be safer because there is more financial support.

Although some Altcoin succeeds in experiments, many are skeptical about its usefulness. No Altcoin has such a large infrastructure as Bitcoin and many people just use Bitcoin for daily trading.

Bitcoin can be called by simply "dollar digitized". This currency is quite similar to the US dollar, except for the complex rules that come with the banking system. This is not a technology. Bitcoin is not a company either. It is your own money, stored in digital form.
What makes Ethereum different is technology, not cryptocurrency. Ethereum coin is called "Ether" and, like Bitcoin, Ethereum can be bought/sold, and used by investors to call for investment in the ICO. Both Bitcoin and Ethereum all work on Blockchain technology, but Ethan's Blockchain is much more powerful. If Bitcoin is version 1.0 then Ethereum is 2.0, which allows building decentralized applications on its platform.
