it is correct i think. bitcoin is an alternative currency. and blockchain based cryptocurrencies are a solid alternatives for nowadays financial systems. decentralized solutions for traditional banking system is going to rule the world in the future.
I hope so. Because as of today, we're still living in the traditional banking system which is centralized. Without a doubt, cryptocurrencies like Bitcoin and Ethereum has proven to be viable alternatives against the current financial system. With their decentralized design, anyone can own a share of these cryptocurrencies without fear of downtime or censorship. But, centralized fiat money still has the lead, probably because they're backed by central banks and governments.
These entities have been carefully researching blockchain technology, to migrate their existing solutions into a global distributed ledger which is secure, fast, and transparent for anyone to audit. Due to the success of the Bitcoin blockchain, many people have used it as an alternative currency for troubled times. But, I think that once fiat money transitions to the blockchain, then cryptocurrencies would serve no purpose at all.
