Hi gorsek1,
The current diff is shown here https://explorer.hanacoin.com/. We haven't added a graph yet, however, the other pool explorers have graphs (https://weekendpool.net/explorer/HANA). A full list of alternative pools is on our website https://www.hanacoin.com/#alternative-mining-setup

We do not have any immediate plans to list on an exchange. We are currently in the accumulation phase and building up the brand.

Our discord covers some of these questions, feel free to come and join over there: https://discord.gg/Utq9z9R
