Telcoin aims to provide instant and low cost payments worldwide but in my opinion telcoin fails to do it. Their token is build on ethereum and we know ethereum is not instant. Maybe their interface shows the money instant which other services and bank also does so there is nothing special.
Why to choose Telcoin to send money installing all the apps, having cards when you can use fast coins like Stellar (XLM).
They also say low cost payments, only 2%, which is also very high compared with what you can do using fast & secure cryptocurrency.
I believe Telcoin makes cryptocurrency looks bad from the point of view of advertising. "We are blockchain based but we ask 2% for each transfer." That's why people still use Western and other services like that.
