3. NULS wallet的頁面，三個綠色方塊很突兀，不知道要表達什麼
Some suggestion as below,
- The movie can be changed into an embedded one, and the click rate may be improved
- The top option bar should be fixed. The benifit is when user scroll down the page, and it's still working.
- For NULS wallet's page, there is three green squares. What is that function? If there is no fuction, please remove it.
- For the Roadmap, part of ICE/Water/stream three options are not clear
