Super slow to open, Website front-end sucks and do not explains anything. You need to show them testimonials of previous users and all big things to do. It would take a lot of time, money and hardwork for years to be successful
I tried to open it too, it shows that the URL is suspicious to open. I still allow it to run, it starts to load, and takes a lot of time and I close my browser as I am not taking any further risk. This is the real feedback which many people will get once they open your site / dapp. He needs to host it on a faster server or fix the slow loading issue, whatever is the problem needs to be fixed?
Don't sell anything until you have something to sell.
Do you plan to develop your technology with the revenue?
This model that worked in 2016/17 to generate revenue through ICO even before developing the project will not work in 2024 anymore. People have seen enough scams that no one is going to invest in even a running project, to get the investment for only the idea that will be materialized on people's investment is never going to be fulfilled and is already considered a scam even if the OP has no bad intentions.
