Hi, I have a company making videos, so I could probably help you.

We make high-level commercials, specialized on CGI animation and motion design, so I guess that would be the right fit for an app. Obviously, you don't need the highest level commercial but I can make some sort of deal with you and figure out exactly what would have the biggest impact for your app most.
I like to support companies in this space.

I would love to see the bigger adoption of cryptos of course so it`s kind of selfish, but for the greater good, I hope  

We have made many commercials for apps with great success, I would suggest using human element together with graphics design (showing the app in a nice eye-catching way). Probably you don't need actors so you could use stock images and combine it with an app.

You can get some reasonably nice shots from stock like:

depends on what you need to show

I would also connect those images with design something like this (except better designed this look like from 2005):

Just send me PM if you would like some help, I can make your video even for BTC.
And yes my profile is new I have just got into this forum specifically for this reason to help other companies in crypto with growth.

I am also going to make video show about crypto with interviews and such + thinking about non-profit learning videos for general public,
the thing is we are one of the best animation and design studios in Europe so I think I could really make difference in public opinion if I use my marketing/storytelling skills for that. Maybe some patreon page where people could support it.

I don't know well see.

Cheers, have a nice day Everybody.
