When you start dumping huge amounts on buy orders, the price will go down.

[phil__65]

because if the exchange does not have a big exchange volume for LTC such a sell would eat up a lot of buy orders and would push the price down a lot. watch bitcoinwisdom for some time at full zoom, you´ll understand then how buys/sells adjust the price.

[deodecagone]

right, if you'd sell 7k LTC you would probably bring the price down to half of the value and loose significant part of your LTC-BTC equivalent. Volumes are not there for such transactions

dump the 7000 ltc in 2 weeks, split in small orders, on several exchanges.

Thanks so much for all the replies!

Now, please, how much do you think would be a "good" amount for selling today in:
Bitcoins
Peercoins
Litecoins
Dogecoins
Some other coin that could be a good example

the best example is to think about the average exchange volume, on the exchange(s) you will be trading on, or the average across all.

if your amount to sell represents a significant % of the average volume over a given time period, you will definitely affect the market.

example

you want to sell 3x the average hourly volume of LTC on cryptsy.

you will push the price down if you try to sell it all in an hour because you exhaust all the buy orders at the currently traded price. if you spaced it out over a day the effect may be minimal.

if you have say 10x the average hourly trading volume u will start to have a lot of problems trying to get in or out quickly. if you have half or less then it shouldn't be too bad.

this is just a rough idea how to figure it out for yourself.

7000 LTC ($154,000 on current prices) is an appreciable, but not really a huge amount. Walls in the millions of $ appear on btc-e fairly regularly. Now 7000 BTC equivalent of LTC (200K) -- that's likely to cause lasting damage.

[hvezdasmrti]

at btc-e is 7000 LTC a spit into sea lol. Just buy when someone buys huge amounts of LTC. No problem to see thousands of LTC/BTC per hour volume if someone does that. Even at altcoins.
I recommend you to use BTC-e because it usually works as an anchor of cryptos, e. g. when china dumped, btc-e was the biggest buyer of chinese coins so the crash was not as disastrous as it should be.

IF you are  trading cryptos not traded at btc-e than its much worse, because e. g. at coins-e there is a problem to sell even one bitcoin adequate price. Sometimes i buy for 0.1BTC and there is nothing left at this or similar price.

Thank you, awesome answer!

I tried to learn this now by myself, so I visited Cryptsy and headed to https://www.cryptsy.com/markets/view/3

Then there is that graph where you hover the mouse and it pops something like "Volume: 1,000.00000000". The average you mentioned I have to figure by hovering the mouse and calculating, or is there an easier way?

From what I could gather, the hourly average is around 500 LTC, isn't it?

there are many different sites which carry statistics, I am not sure the best but just have a look around at the main ones. coinwarz shows exchange volume column, its showing last 24hrs.

a good exchange would include this information in a small information window on the top right area detailing 1hr and 24hr averages, and volume weighted average price. it will be up to you to find the best source to determine this information on your own until cryptsy or your preferred exchange decides to implement something.

The "scale" factor in markets in Open Transactions hopefully will help with this kind of thing, because if you want to deal in thousands of something instead of individual ones of it or tens of it or hundreds of it or lots of ten-thousand of it etc you trade on the 1000-scale market.
