Two minutes of google time finds articles going back years that suggest it's not an new idea. Just an idea you disagree with. You're right it does seem to be mentioned more in the last few months. High fees and the political problems you mentioned are likely primarily responsible for this.
articles on the investment oriented internet which are talking about how "bitcoin can be a good store of value on top of other things" is not equal to a lot of people in the community saying "bitcoin is only store of value and nothing else".
I wonder why so many exhcnages are adopting or have adopted Litecoin specifically instead of other, more popular altcoins?
You also see it with the large Chinese exchanges, they almost exclusively have Bitcoin and Litecoin listed.
Perhaps it has something to do with the fact that Litecoin is pretty similar to Bitcoin and supporting it doesn't require that much work?
it is the oldest altcoin.
it has a couple of good developers.
it is copying code from bitcoin, that automatically means it is good (bitcoin code is reviewed and tested, extensively)
also it is possible because they are mining it! the big mining farms are in China.
