trust wallet actually is a newborn wallet and most of the people who posted here are newbies and I believe they just promoting it just like this thread.
I don't think so.
Trustwallet is owned by binance and is well-known enough. I don't think they need that kind of promotions. Trustwallet has been downloaded more than 10 million times from
Google play store. That's 10 times
Coinomi's downloads.

Of course, I never recommend anyone to use a close source wallet like trustwallet.
