Who can diagnose Toronto's water supply?

I myself recently learned that in the UAE there is such a cryptocurrency as dubacoin. This cryptocurrency was launched by ArabianChain Technology. Dubaicoin was created for the people of Dubai, but is available to the whole world. Cryptocurrency can be used as payment for goods and services, so it has aroused the interest of many. I was even able to find information on how to buy dubaicoin https://minery.io/ae/blog/how-to-buy-dubaicoin/ . Many people say that dubacoin is an unreliable coin. However, the coin is listed on major exchanges, which suggests otherwise.
