The pirate coin arrr is it a scam?
I don’t consider it to be a scam as scam means that devs are dishonest and want to do a runner with all money, but they support communication, I mean interacting with the community, so I don’t think that they are scammers.
In terms of investing in it, I am not sure about this. This project’s idea is privacy, but considering Monero, privacy is not a priority today.
