Bitcoin already has a unicode sign, which is plenty. We don’t need an emoji, we need better user access to the full unicode set. (To date, on both mobile and desktop, I have to sometimes websearch specific characters and copy-paste, and not all emoji are displayed on my PC Firefox browser, though it’s better now than last year). Also curiously, the Lemmy website text editor emoji picker only places an emoji at the end of the text, not where the cursor is (and adds a space I don’t want).
The current Emoji library has a frog face, 🐸 not a frog body. That’s a higher priority than a bitcoin. I could see some kind of generic crypto coin, maybe. Maybe.
On a parallel subject, I do think the international community would do well to create a decentralized currency, and I do think blockchain may figure into this, but it needs to be secure and allow for anonymous transactions, and not allow for tampering with the ledger. Bitcoin has failed on all three accounts. We need a better, more robust system, but it seems all current cryptocurrencies are practice, and toys for prospectors and gamblers until we make a robust one.
I absolutely do not want to encourage the ransomware industry.
