The pirate coin arrr is it a scam?
No! I don't think so. You probably don't know that it was launched in 2018 and the team is still active as they recently listed their token on kucoin (on June 22, 2021)From my point of view kucoin is a good exchange which often lists only good projects.
But it should also be remembered that they do not think twice before delisting.
If the kucoin team don't get the trading volume as per their requirement, they could delist it any time
Anyway,
If you want to know more about the pirate coin, then here is it's the announcement thread link: https://bitcointalksearch.org/topic/annpirate-chainarrr-a-zk-snarks-only-blockchain-secured-by-dpow-4979549
I think this project is fine, some projects work slowly, it also suffers from it and it is listed on kucoin exchange will be a good project. And not every coin performs in the bull run. There are some coins that perform after the bull run and we can call them long race horses. And maybe that's one of those plans.
It's a pitty most people won't allocate a minute or two to inform themselves before writing some arbitrary uninformed comment on threads like these. Even worse is when people believe these comments at face value and act upon it. I understand that there is so much information out there that it because quite difficult to conduct proper research, which is why I prefer to provide further reading material and links for those to do their own research. I also encourage people finding other independent ways of researching projects.
