Over 850 millions of people use alipay as means of payment mostly in china and i heard lots about wepay as well, i come to think of it that what if bitcoin was been used in their places instead? if alipay and wepay can get to where they are today then altcoins have all the chances of survival as well. Wepay and Alipay are just online payment solution, crypto can do better.
Real use cases plus real life working products, let these two be your main focus when picking altcoins to invest your money on, do not listen to those saying 'dump altcoins for bitcoin' when you are holding solid altcoins
Cryptocurrency may grow to the extent of being used by millions of people as a means of payment but its important to consider the fact that cryptocurrency has lost her reputation as a great medium for payment and would need the support of a vast amount of people to regain her place.
