You cannot know which projects can become scams. If the project deposits 40% of their assets to a third party, I think they will not be able to continue the project. You want to get usdt, eth, btc but this is not possible.
Nothing is impossible. But such a step will not be interesting for projects that are conducting an ICO. The goal of any project is not only to promote a project using a bounty program, but also to create a target audience that will use this platform.Nobody needs a cold calculation. Everything should be done with LOVE
