Then if you would want to accept donations or payments, anonymity is only possible with cryptocurrencies and cash-by-mail. The easiest one (anonymity wise) is Monero and the most popular one is Bitcoin.
Can we just stop with the "Bitcoin is anonymous" bullshit here?
Anybody here is smart enough to know better, so it just earmarks you as another fucking crypto-shill.
And don't work. They were revealed to be useless way back when the Magic The Gathering Online Exchange crypto grifters pulled the first high profile scam, and they got hounded through all the "mixers" anyway. Chainalysis has been able to see straight through "crypto mixers" for almost a decade. (Yeah, there are probably way that right now you can't track bitcoin through other crypto currencies and back into bitcoin, maybe... But we are now a long long way from "good advice to an old guy who want to sell macOS utilities anonymously")
Pretty irrelevant here but for your fucking information, with significant expert effort, Bitcoin *can* be also anonymous against big actors.
Each address is a random pseudonym. A wallet is a collection of pseudonyms but it's secret that they belong together. Except network analysis can infer that some of them do. Pseudonyms are persistent, can't "change them", only transfer coins out of the pseudonym to a different one, i.e. log a transaction.
Care to point to Satoshi’s real identity since anonymity in Bitcoin is bullshit?
The only weak points are exchanges. The OP can decide how anonymous they want to be - complete anonymity would imply not exchanging to fiat at all.
I don't disagree that most of them are not practical for a rando developer who wants to be anonymous, but I'm still annoyed at "the only weak point is...".
Anybody can start a new crypto wallet and receive funds into it, and then make transactions and keep that value on-chain to remain anonymous. There are a number of anon devs in the Ethereum ecosystem doing just this.
With enough effort your IP might be traceable if you do something like mint a token from a compromised website. But advanced methods also exist to break anonymity in systems like Tor, VPNs and cash which we often consider to have strong properties of privacy and anonymity, and to this nobody would refute as “bullshit.”
