For people that are far from their family and friends, reaching them and communicating with them is something that is of utmost importance. The presence of many social applications which have video and audio options are a great way to stay in contact and in touch.
However, not all of them are active on social media, also, when there is no internet access we still need to use the traditional calling method to reach them.
Over the years, I use an application called MVOIP.:Mobile voice over the internet protocol.
This is an app that houses various services to call traditionally.
The service I use among those offered is the one by frynga.
In recharging frynga, one of the most interesting part is there is an option to recharge with cryptocurrency(Bitcoin and bitcoincash).
With these options I feel adoption is permeating the most day to day activity that we do.
