What is a cryptocurrency only the veterans can remember?

I've been into cryptos for 5 years now, and yesterday I had an interesting talk with my buddy who's been in it since 2015. We reminisced about the good times back then, even this subreddit was a lot different.

Then we quickly got to "which was the most pathetic crypto" and soon after dentacoin came to mind. Like a crypto for dentists, guys, this was the shit in 2017. This crypto was going to revolutionize the dentist industry...or idk.

Obviously Waltonchain came up, and for those who don't know, they had a Valentine's day giveaway on Twitter, and they rigged and cheated it, and tweeted a message that sounded like an average joe excited about winning their giveaway. It went downhill from there very quickly.

What is your favourite cryptocurrency that you think not many of us remember? It can be a legit good project, or a token with no utility, a scam crypto, anything.
