Joe Rogan promotes BTC wallet on phone

So I was trying to get my buddy into ETN the other day and he was saying he didnt care about any cryptos because Joe Rogan (UFC) was promoting a one card that was on your phone and you could pay with multiple accounts with it including your bitcoin.

I think I found it. https://www.reddit.com/r/Bitcoin/comments/7sp0op/the_cash_app_has_a_bitcoin_feature/

Not sure what to make of it, but it seems similar to ETN platform. Would it be beneficial to have a celebrity promotion like this? I know we haven’t started marketing, but this ecosystem doesn’t work if we gain the east and lose the west…if you know what i mean.
