I want to get an answer to this question from the community of Bitcoin.
The opinions on fungibility go like this:
- No: Many places buy the "taint" nonsense and treat bitcoins unequally. Therefore, you might be discriminated based on your coins' history.
- Yes: No matter the history, 1 BTC = 1 BTC, always. The protocol doesn't treat them differently, and we shouldn't interact with businesses that enforce this "taint" notion, which is evidently based on inaccurate fallacies.
I'm personally on the latter group. Third parties can treat them however they like. They're just losing me as client. Decentralized solutions treat all coins equally, as they should.
In the Monero community, there is a prevailing perspective that due to these businesses, Bitcoin is not fungible, and Monero is. My question is: have you ever paid a business that buys the "taint" nonsense with Monero? Does it make any sense to enforce this BS while accepting a completely private currency that you cannot track? In my view, if a business performs blacklists on my bitcoins, it absolutely doesn't accept Monero. You either accept both Bitcoin and Monero as fungible, or you blacklist the former and delist the latter (due to your inability to track it).
Bitcoin is not fungible, thanks to blockchain technology where absolutely every transaction is recorded. I bet that if Satoshi sends me 1 Bitcoin from his wallet, I will be able to sell this 1 Bitcoin very expensively or probably my wallet because I received Bitcoin from satoshi, this will be the rarest moment and it will give it a value. You have already heard about halving block, rare sats and some other nonsense. The fact that people value things like this means that Bitcoin is not fungible.
If there was no transaction history on blockchain or everything was encrypted and impossible to decrypt and we don't know who sends and receives money, then such a Bitcoin would be fungible. Monero is fungible but finally it all comes down to what we personally think. For me, Bitcoin is non fungible but for others, it really is.
I agree with you on the last part, if business blacklists Bitcoin, it won't accept Monero and if it doesn't blacklist Bitcoin, it will accept Monero.
