Let's look at just the past 30m... there were over 1 BTC worth of buy orders at .035-.036/1000. At a rate of 0.025 BTC per LTC, that would put 2000 GWC (0.070-0.072 BTC) at 2.8-3 LTC. Or people could hold out a little longer and get more than that. I'm not sure how 180%-200% more is somehow "slightly more" but if that's seriously how you view things, send me $2800 and I'll return $1000. Look at it as being a nice gesture, considering $2800 is only "slightly more" than $1000...
That or maybe you need help with math. Might I suggest using a calculator next time? I have the feeling you've been losing a LOT of money due to your failed mathematics.
Which exchange are you looking at, maybe there's a third exchange carrying GRW that I haven't been seeing. I don't see either exchange with that kind of volume.
https://btcltc.com/home/index/grw_btc <-- Less than 1 BTC in the last 24 hours, those were all buys off a single sell order at 0.000035 (which is the price you are quoting above). The highest buy order is 0.000020.
https://coinex.pw/ <-- Here the price may be a little higher, but at 509 GRW in the last 24 hours you won't end up selling much. EDIT: That 509 in the last 24 hours isn't right, it says that the last trades were 4 days ago.
It is perfectly fine if people want to hold their coins, but right now it is disingenuous to suggest that anyone could sell $2800 worth of GRW at 0.000035.
