As far as I know, the project was supported by a large user community shortly after it was set up. But afterwards, yyani is not serving at the moment which really surprised me. Yet, as the project had great goals and objectives, it seemed that there was little way for them to achieve their goals.
According to some information, there are claims stating that the project was changed and served under a different name, but personally I do not believe these claims and think they are false. Currently, the website of the project seems to be owned by a different company. In addition, it is possible to see that social media accounts have been deleted.
Despite all this, the YEED token is frequently traded by many users. Currently, the supply of the token in circulation seems to be high enough, and since the market value of the token is also high on the Coinmarketcap platform, I think it will not be a problem to have the token. However, the value of the token is very low. I have been following the charts of the token lately and I see that the trading volume is increasing every day. Also, the YEED token is traded on several large and trusted exchanges and has many trading pairs.
Generally, even if the project is out of service, the token is still there, so it seems to continue to be used.
