Is it possible to send bytes using other chats? or only through the byte wallet? I think if you add a similar function to discard or Slark,
it will be a huge success.

Not really.
Most people are afraid of having to install a new app without any benefit from it.
Textcoins are brilliant, but completely worthless without use case. They are also again only the second step before the first.
In the end, the coins will be forgotten and lost in nirvana.
