My bitcoin reward keeps decreasing!?

[wolfEXE57]

So I've been mining for about 2-3 months non-stop using 4 antminer U2's and when I first started out I was getting a little over 0.00002000 BTC , now I'm only getting 0.00001300 is there any reason? I'm using a raspberry pi as the controller hub all of my miners are at 2 giga hashes and don't really fluctuate. The only thing I could think of is my pool which is shush pool.
Please help!

The total hashrate of the network keeps increasing. The more devices participate, the more calculating power there is.
The network adapts, by increasing the difficulty, so that blocks keep coming at 10 minute intervals on average.

Your 4 miners have a certain hashrate, which doesn't change. However, your proportion of the total hashrate gets lower and lower, since the network gets bigger and bigger. It's normal for your income to get lower over time, and it's the nature of bitcoin.

i am seeing questions lime this far too often now. People really buy and mine without understanding the basic principles. ........ the world is doomed

3 months ago, the difficulty was 29,829,733,124.
Today, the difficulty is 39,457,671,307.

The difficulty has increased 32%, and so your mining reward has decreased accordingly.

Bitcoin difficulty adjusts every 2016 blocks, 2 weeks on average. The network would adjust the difficulty according to the average timing between each blocks. The network would then increase or decrease the difficulty to try to make the interval between blocks to be 10 minutes. If the 2016 blocks take more than 2 weeks to solve, the difficulty would decrease and vice versa. The higher the difficulty, the less your earnings would be. The difficulty has increased tremendously therefore, your earnings has decreased.

this is the basic of all basic, the diff simple rised and you gain less, now the diff is declining a bit

It has always been this way. This is what makes societies go round

[Sindelar1938]

That's the way it works. Get in the mining hardware arms race or stop mining.

Assume two variables. x - your mining power         y - total mining power.

x remains the same.

y keeps rising and difficulty rises.

Your return = x/y falls.

More people mine = less coins per miner

Should have just bought coins and held on to them

[rz20]

1 - Hash rate has grown 30% in 3 months.
2 - More people mining in your pool.

[lynn_402]

1 - Hash rate has grown 30% in 3 months.
2 - More people mining in your pool.

It makes no difference that there are more people mining in his pool, except that the payments are more likely to happen often and to be regular.

What price you (or your parents) pay for electricity which is consumed by your HW?
As you understnad the difficulty in the mining I think it`s important to understand your cost too.

Have a look here on Bitcointalk around, get some basic informations.

Good luck

If I had 4 Antminer U2's running I wouldn't be pool mining for chicken scratch, I'd be solo mining for the BTC lotto.

If you didn't read up and research about mining rewards vs difficulty vs network hash rate, don't know what to tell you.

If you were wise, I'd get off Slush and mine at one of these:

http://solo.ckpool.org/

At least this way if you have the luck of the Irish, you'd get 99.5% of a block or 24.875 BTC instead of mice droppings everyday.

You will need all the luck of all the Irish in Ireland to accomplish that. 

The difficulty might decrease, if more solo miners pull out, but the days from making money from solo mining, has come and gone.

[goosoodude]

The total number of coins generated per day is kept fixed. So if more miners are mining the difficulty to mine increases to keep the coin generation number fixed.

Next year July guys,  the block halves, be ready.

the higher the difficulty the lower the rewards.  you can use a profitability calculator to estimate your reward
