Bitcoin is the king of store of value asset that can be easily moved across borders without any intermediary/3rd party that unlike gold, stocks, bonds, real estate, is largely free from any central bank led price manipulation.
Bitcoin is ultimate store of value and its popularity has strengthened over time and
maximizes value compared to any other altcoin...why?:
If it can be shutdown, and have assets frozen by a bank or government, there would be no value
If it wasn't secure, there would be no value.
If it wasn't immutable, there would be no value.
If it wasn't globally distributed, there would be no value.
If it wasn't so strong, open-source decentralized and unstoppable, there would be no value.
If it wasn't so scarce, there would be no value.
If it was easy to spam transactions, there would be no value
If it was stopped after all major banks on Earth banned in 2013 to today, there would be no value. (say "bitcoin" when transacting and watch the block of the transaction. simple fix=never mention "bitcoin").
If it didn't have the history of 8+ years (and still no hacker can exploit bitcoin blockchain), there would be no value
If its development wasn't decentralized around the world, there would be no value
If there was central "leaders" or foundation for the coin, there would be no value
If it was exactly like fiat and only did transactions, there would be no value.
Bitcoin has all the characteristics needed combined to make the most value and increasing more than any other financial-asset option coming from the manipulated fiat central-banking debt-system.
