Grin did not have all that much going for it in the first place. Ooh so it's a privacy coin, wow, will it ever have a large potential userbase besides the paranoid and drug users and pushers. If I am way off here, please tell me why Grin is going to be a huge winner going forward

I don't think that the bulk of people who like anonymous cryptocurrencies are drug dealers or criminals. Anonymity is worth a lot these days. It's just that few people think about it.
