I was suspicious of them from the start.

Every now and then there is a coin that gets shilled hard here in the altcoin forum.  Bitconnect, verge, bitcoin fuji, and oyster pearl about three four months ago.
I am always suspicious when a no name, no use, shitcoin suddenly gets pumped and pushed hard.
Many jumped onto these forums proclaiming it to be better than iota and a hidden gem and all that.

I tested it out and wasn't really impressed.  Nano (previously raiblocks) just blows any "3rd generation" coin out of the water and it has market awareness.

And now this.  This is the magic of blockchain tecnology, it is all algorythms and mathematics, it doesn't lie.
So if you see that large amount being dumped on you, then that is exactly what happened.
They can deny or change the narrative as much as they want, but it doesn't change the facts.
that's why it is important to looks at things like a projects github or just explore their blockchain.
If it's hard to make sense of the tech side, just screenshot it and ask about it on reddit or here, there is always a techie that can interpret it for you.

Good luck to all of those heavily invested in oyster pearl.
You are going to need it.
