The mother of all crypto scams is bitconnect. I can't believe that piece of garbage was once a top 10 coin. A lot of suckers fell for the hype and got blinded by greed.
I remember this years ago that one of my friend ask all of us to join bitconnect including me, after several week he just stopped talking about it eventhough I keep asking for it. That's how I know cryptocurrency for the first time, by losing some amount of money first. That's a bit ashamed that I got scammed as my first experience in crypto, but that's also such a blessing that I knew about crypto because of that.
Ah, yeah, bitconnect, that was the most famous ponzi coin introduced in this space that got so many supporters and yet it takes years before it got taken down. The most hilarious and unforgettable of this coins is because of its memes of the promoters singing with this coin lmao.
