Incorrect. A couple of coins exchanged for extremely small amounts of money (I'm talking $20.00 worth of bitcoins for some grin at ridiculous prices) doesn't mean you or I could have actually sold at $200. Maybe one person sold 0.1 grin for that price. Great for them. Also, even if there was significantly more volume, on day 2 (after the 1440 block waiting period for coinbase transactions) the price would have ended up tanking just the same. Btw, the price started at $200 and dropped like a rock. Where are you seeing a pump from $3.00 to $200.00?

The grin community was already aware that Theymos liked it because of his post in the ANN thread. The technology is amazing. I'd suggest doing a little research. It's not bitcoin with a fancy hat and a new name, it's a brand new coin with brand new untested tech. Even if this impliment fails I think mimblewimble is here to stay (even if not in this exact form). Saying that this announcement somehow caused hype is hilarious. Why wouldn't the other post cause this amazing hype?

Lastly, how many grin do you really think bitcointalk has gotten from this so far? I doubt it's creating the amount of hype that you're talking about. I'm all for a 6666.66% pump, but it's not going to happen because Theymos decided to accept grin for copper membership etc. You and I both know that.

If he's wrong about grin I guess you're going to start a lawsuit right? That's the only sensible thing to do. /s
