TLDR
If you say Shitcoin, you should include the fiat currencies as well.
I did mention, but you missed it (TLDR).
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.
Definitely decentralization, but back in 2011 - 2013 I don't remember ever thinking about using Bitcoin as a hedge against inflation, it was for payments and the wild west beginnings of speculation/trading. People dismissing Bitcoin in those days usually talked about ponzi schemes, bubbles and scams (remember Pirate@40?), different tune now. Although after accepting Bitcoin payments as a business since 2011 I did notice that by waiting a few months or so before cashing in usually meant significant increase in value compared to other payment methods like PayPal and Credit Card which only meant fees (around 4%, nothing positive at all).
If you are really interested in free (as freedom) money, you should not be interested in getting any support for shitcoins.
I'm thinking "free" as in not directly possible to block by government when you disagree with them which is becoming reality with credit cards and even bank accounts as of late. Are you thinking of something else?
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.
Agreed.
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?
Interesting, to me Lightning is the perfect fit but it currently lacks adoption, and somehow people can't think of using their Satoshis (because Lightning is Bitcoin), only stack them.
