I recently got to know about the existence of privacy coins and what they mean. I can imagine why anyone will be interested in its usage being that it's offer more anonymity that the bitcoin ledger. But can such implementation be incorporated into the bitcoin blockchain and make it as a choice for those that don't what input and output be publicly viewed on the blockchain?
Bitcoin itself is already privacy, I think the anonymity of Bitcoin is enough even though it's not like the monero and dash (because indeed these 2 coins are privacy coins). If you want to add this, it is related to the implementation of options for those who do not have public input and output on the blockchain that requires hardfork as @ETFbitcoin says.
It would be better if the Blockchain BTC stays like this so that everyone can monitor.
I love BTC like this, its more than enough.
I understand why you would love the current bitcoin network this way. I do too. But I think for the bitcoin maximalists who do not want go outside the bitcoin blockchain to make use of options that features to either make a transaction completely anonymous or default.
