Elianite, no offense, but this doesn't belong anywhere near the Encyclopedia. If the promoters of Onecoin and Paycoin paid a few dollars on Alipay to have a copper coin produced for the purpose of milking suckers into investing, do those belong in the Encyclopedia as well?
Yes, that coin would absolutely, most certainly belong into the encyclopedia. The purpose of the book is to record and categorize coins; and through them, preserve and curate the history of crypto-currency. Any coin that has any significance, story (negative or positive), or originality belongs there. The only coins that were not previously included are those for which not enough info exists to make a half-complete entry.
Most people agree that Onecoin/Paycoin was a scam. If a coin was produced to support the scam, I would very much consider it worthy of study and collection.
The book also has many pages dedicated to Coinographic, which turned out to be somewhat of a scam. that story is recorded. Should it instead be erased and forgotten?
