Same, only I would pick Bitcoin & Litecoin since they have people from pretty much everywhere in the world wanting to have it. Bitcoin should get into worldwide usage if there is enough people using the coin though that won't happen any time soon since there's also people that are really against Bitcoin for some reason.
If Bitcoin & Litecoin share their technology then it would be a pretty strong duo if it was possible to make it work.
Yeah. Both Bitcoin and Litecoin have a wide audience, not to mention that they're greatly known in the crypto space due to their years within it. Whereas Bitcoin is the most secure cryptocurrency, and implements a deflationary model, it works best as a store of value, while Litecoin can serve as digital cash to process our daily payments in a fast and easy way.
They make a strong duo indeed, and are prone to survive for many years to come. Especially Bitcoin, since it has shown to grow stronger everyday with the wide acceptance from people in the mainstream world. The best thing about Litecoin is that it serves as an experimental sandbox for Bitcoin, allowing to test some of the proposed features for the pioneer cryptocurrency into it, before they could become applied within Bitcoin itself.
When SegWit became successful into Litecoin, it gave a green light for Bitcoin to begin adopting it as well. And with the recent surge of SegWit2x for Bitcoin, things are going to change drastically for the pioneer cryptocurrency if successful.
That is why, Bitcoin and Litecoin should be within the favorites list of any cryptocurrency lover or supporter like me. Just my opinion.
