I am presenting my new Concept:

XEM - X(CountryLess PreChar) Economic Money

Algorithm: Proof of Uptime (PoU)
it will be tracked the uptime of the client. The longer it's online, the higher the chance of being chosen for solving the next block.
This makes of course only sence, for one ip-address, so the system will check, that all uptimes for the current round are coming from different ip addresses. Otherwise someone can fake multiple uptime accounts.

For preventing bot nets and multiple vps:
Every miner has to be registered on some institution, where they Check for the passport.
The miner Gets a Mining Key.
This is only for "Mining". Normal wallets doesn't need that registration.

Advantage:
- no wasting engery as with PoW
- no unfair advantage with a big amount of coins as with PoS
- high availability of systems
- 51% attack nearly impossible

Coin Maximum: about 1 Billion
5 minute transaction time (288 blocks per day)

Coin Distribution
Beginning: 58000 XEMs every Block
halfing the amount every 8.640 Blocks (about 1 month)
Total Coin Distribution Time: 12 Months
After that 12 Months only transaction fees.

"Premine" for development and marketing:
12 hours => about 0,83%

maybe its better to buy them a few gram gold instead ;-)

maybe atm nobody is interested in trading quark?

There will be two possibilities.
Either bitcoin will be at about 500 thousand or at 0.
The blocksize problem will maybe never be fixed and other cryptocurrencies will outperform bitcoin...

Maybe a down of the server?
Did you update the java version?

The best thing for a newbe is to mine on new currencies.
With Bitcoin mining its impossible to make money at the moment, unless you have an uncle, which owns a hashing hardware company.

Litecoin mining is still available but will also be harder the next months, i guess. Maybe we have luck and there will be a nice BTC crash, so that LTC is falling as well. Then there will be maybe decreasing the difficulty there.
If that happens I expect LTC to raise again latest on the next BTC hype next year.

Best thing is, to buy yourself a nice computer with nice GPU(s) like R9 290x and mine currencies like NVC, PPC or YAC.

I bought a 25GH miner in April from Butterfly Labs. It came 2 weeks ago.
When I ordered it, I would have earned about 0,25 btc a day. When I got it, I only earned about 0,02 a day, less than 1/10.´
As difficulty goes even higher at the beginning of the next year it will take more power for the amount of btc, than the btc can ever be worth.
There is always better and better hardware out there.
At the moment you can't buy, because all companys prefer to use their hardware themselves, until the profit is not worth it any more...
Why should a company sell something, what gives them more profit, if they use it themselves?

You have to wait, until we come to a point, where the hardware doesn't get better. I think this will take at least another one or two years.
Then the hashing rate maybe won't increase any more and you can buy a steady income machine. With very less income per $ spent, but for a very long time.
Maybe we will even never get to this point, because also on cpu speeds we thought there will be and end somewhen and there was not for 30+ years now...

This will be about the 3rd "crash" then.

look at the chart:
June 2011 - raising to 30+$ and crashing to ~5$

April 2013 - raising to 250+$ and crashing to ~50$

Dec 2013 - raising to 1200+$ and crashing to ~ 600$
yet, maybe a little more, but anyway...
my further prediction will be:

somewhere in 2014:
raising to ~6000$ and crashing to ~1000$

somewhere in 2015 or earlier:
raising to ~30000$ and crashing to ~5000$

and so on... up to about half a million, what's it's real wearth...

you can compare bitcoin to gold.
The current world wide gold amount is worth about $8.5 trillion;
Dividing this to the 21 Million of maximal bitcoins gives one bitcoin a value of:
8 500 000 000 000$ / 21 000 000 BTC ~ 404 761$/BTC

at the actual gold price...
