Great insight there on Safaricom adopting cryptocurrency as a value add to its products. Sadly, its majority shareholders who would determine its direction are best served with the current setup (traditional finance).
If anything, the ideal application of cryptocurrency payments would mean less revenue for them since their role as a middleman is greatly diminished.

But, in the same way big companies rubbished the internet in its early years, then eventually adopted it after realizing its potential, the same case is to current corporate entities with crypto. But all in all, eventual adoption is imminent.
