This is probably the last thread to get any support for altcoins (aka shitcoins), but not for lack of trying.
What do you guys think about payment systems? Shitcoin worse than Credit Card?
...
TLDR
If you say Shitcoin, you should include the fiat currencies as well.
The pivot points are still: (De)centralization and Inflation.
Bitcoin (the protocol) was created to solve both, very basic problems of financial systems, while all the other Shitcoins failed to do so.
Sure, there are always some caveats, for example the 51% theorem in regard of Decentralization, but basically using Shitcoins for payment systems is only better (or more widely) supported,
yet.
If you are really interested in free (as freedom) money, you should not be interested in getting any support for shitcoins.
Lightning is a step on the evolution of Bitcoin as a global payment system. Pretty clever, as it also solves a big part of the scaling problem, but that's just my opinion.
Let me transform your original question to be more compatible with this thread's topic:
What does Bitcoin need to replace shitcoins and centralized payment systems?
