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
I think bitcoin could survive on its own even if no other tokens are in the market bitcoin is still what it is today,
All of the altcoins in the market are just a copy of bitcoin and they wanted to replicate the success of bitcoin since in the past years it has a successful technology.
But still it is a unique algorithm and even if they create a token like bitcoin, bitcoin was still the first in this kind of digital currency and already established its market price.
