@maok, maybe you can also help me with the following.
There is one Quarkaddress with 4,2M Quark on it:
http://qrk.blockr.io/address/info/QRHb2CTvGnwwrf6GHrxgQcH2tTAUoGhnC2At 08 January there was 33M Quark on that address. There have been much speculation and discussion about this address in the past.
First was thought it was from an exchange, but we can exclude that after today's calculations (and data from Bronevic) that one exchange had once 33M Quark.
Most probably it is of an early miner. I don't bother very much that (s)he has still 4,2M Quark on it (At one side that person is capable to destroy the complete Quark market, as we have just calculated that the buy orders are not more than about 700.000 Quark at btc38. At the other side there will be of course new buy orders when the price drops).
What I find strange is that this person is sending and receiving almost daily from January 04 till September 20 100.000 Quark from and to this address.
Do you have any idea why one person would send/receive almost daily 100.000 Quark? What is your opinion about this?
Based on the sheer number of incoming and outcome tx'es from a plethora of addresses I can tell you its either a mixing service(which i don't know it exists in Quark) or an exchange. Your confusion regarding the 100,000 in and out is very easy to clear simply by looking at the outgoing tx you'll see it doesn't sends the fix sum of 100K but it sends X amount to an address(most likely a customer or a lower end of security manager/server) and the rest is the change that the quark protocol automatically sends to a new address. Due to the security levels involved in most exchanges they will have managers/servers with different levels of security, which after a while they'll send back to the main/higher lever address in form of a fix 100K sum gathered from all the lower end points.
After looking a bit further I can tell you this service, most likely an exchange, has entered the market around 1-5 Dec 2013 so you must think which exchange adopted Quark on that date or announced that it will adopt Quark(
most likely btc38)
Also after a bit more digging(public blockchain is doing wonders) I can tell you this exchange also has a cold storage address with 18 millions in it(2nd largest in Quark). Most likely that cold address is only accessible from the high end security level probably the owners of btc38 which they'll use it when extra funds are required. Similar to them at quarktalk.org we also have a cold storage address which is the public one(QUARK957iywYSpgkYi9gbW3pFtLszeU7wQ) and the rest of lower end levels are kept on the servers for the payouts. Once I'll use the cold storage address and expose my pubkey then I'll move the funds to another cold storage address, just in case the sha256 algo gets broken ;-)
No one can destroy a crypto currency by selling their coins, what they'll do is 1. deliberately financial self-harm and 2. open up the market to new adopters which will take advantage of the low price. This is the reason you see all the struggle with Bitcoin price going back and forth this year from the $400-$500 levels, this used to happen when it was $10-$11, it used to happen when it was $100, eventually you'll see that no one will commit financial suicide, especially in Quark whose full emission has already taken place(the extra 1 million minable quarks per year aren't sufficient to harm the price by an evil entity, like for example mining conglomerates can and are harming Bitcoin price)
