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
You said all the facts but one of the issues is, many altcoins are even yet to achieve what they are set to fulfill, so how can such coins compete with already built platforms like wepay? This is one of the problems this space is facing and until it is tackled there will always be limitations. There are many altcoins still trying to break boundaries but they need to do more, if beating these platforms will ever work out. On the other hand, only few of these altcoins are good for holding and just like you stated, real life working products should be the main focus. Lastly, Bitcoin can't do it alone, it needs other coins.
