Those things are not scams.

the problem is that you undersell yourself. You don't believe your ideas are worth it. But they are. It actually doesn't matter whether your ideas ultimately work out. What matters is that we need many people like you to be creative to push to try things.
Let us take care of whether its a "scam"or not.

We are all involved in the experiment, and we can't predict exactly where it is going, so we need people like you with knowledge and ideas to experiment.
I'd happily put money into an ICO of yours.
I have done very well in crypto because I'm not afraid to take risks and to believe.

You have something to contribute. It doesn''t matter whether it is perfect.  Do it.

And remeber , if something is worth doing it's worth doing badly the first time.
