I think what rijaljun is trying to tell you is that you could've done this project without getting involved in blockchain tech and cryptocurrencies. You've said so yourself, you guys have already been doing this for two decades now. Why not just get funded privately? Approach some companies or even the government. You could even list this on Kickstarter if needed. You see, by getting into crypto-world, you are also risking the entire project just for the sake of getting a little more funding. Think about it, what if there weren't enough investors for your upcoming sale? As rijaljun said, crypto investments nowadays is pretty low, so the chances that this would happen is high. So, what would your team do then? Return the investments or still try to run the project even with just a little funding? If your project fail, now that you're tied up to cryptocurrencies, you're forever branded as a scam. You wouldn't want that to happen.
