The goal of ADA Coin is to create "3 billion wallets".
These 3 billion people are those whose status is not guaranteed by the government and who are unable to have bank accounts.
The "3 billion purse" is meant to enable these people to protect their assets and save.
Also, in January 2018, the first crypto asset rating by the US rating agency Weiss Ratings was released. There were no ratings above A, but ETH (Ethereum) received a B, ADA (Adacoin) a B+, and BTC (Bitcoin) a C-, second from the top.
This makes it one of the most highly rated crypto assets, and it has a large community around the world.
Although it is not currently traded on exchanges in Japan, it is highly rated overseas and is consistently in the top 10 in market capitalization. As a result, there is a possibility that it will be listed on a Japanese exchange in the future.
