Litecoin has had a great year and possibly bigger things in 2018. If you have ever used Litecoin you know how fast it is and how low the fees are. Recent progress with atomic swaps, lightning network and more features possibly including privacy. A perfect day to day crypto currency for buying a coffee and sending funds to the other side of the planet for next to nothing. Try litecoin, you will like it.
Mastercard and Visa might. Time will tell. :)
