Maybe one day the real Satoshi appeared and did a patent the blockchain. Is this the real purpose of Satoshi's intention to create Bitcoin?
Satoshi's real purpose is to create an alternative digital currency (bitcoin) over the fiat currency which breached the individuals trust to security, privacy and charges of fraction units from one's account.
Will Bitcoin remain valuable or vice versa?
Bitcoin has come to stay and will remained valuable just as gold, if you google the internet, you will find out that bitcoin, gold, share/bond and real estate are the major investment on the trend as at this days.
for sure Blockchain will still exist and will be a large system that will be used by many institutions and even governments.
This is happening already.
If banks actually use blockchain and issue standard central bank currencies or CBDCs which they call, this would be the same as Bitcoin or crypto in general?
The idea behind block chain is that its a public ledger in which anyone can have access to, see but cannot be altered, yet they still implicate all character traits of a fiat cbcd in their currency modules such as zero privacy, high charges fees and centralization. bitcoin uses blockchain but completely anonymous and decentralized.
Fees will also be cheap, transactions can be tracked, isn't this what we want? unlike the current banking system.
This isn't all we want, we demand 100% trust, privacy, security independency (freedom).
digital cbdc is nothing different to traditional fiat banking system and is totally different to bitcoin in it entirety.
