I heard the minium to invest is 50.000$ in bitcoin mining to make some profit. So how more u will spend the more u earn.
Off topic, and incorrect. There is no "minimum" you must invest in mining to make some profit (well, I guess technically if you invest $0). It's all about how you spend what money you do invest. For example, investing $500 into a used S1 would be a very poor choice and not lead to any profits whatsoever.

However, you need to also include the rewards provided by the 25BTC generated per block as Phil pointed out.
No. The net cost of transaction does not depend of block rewards/fees/etcThe net cost is "cost of resources in external currency" divided by "count of items"
Show me that in an accountiing test with bitcoins as a specific example.
you can do it with other items. but the facts are with bitcoin it does not apply.
here is the example you need to think of the net cost of drilling a well is 1000 dollars whether or not I hit oil. so you pull the if out.
the network will hit blocks it is a certainly so the block rewards count.
How or where would you include the rewards/fees/etc in this scenario (obviously not part of net cost)?
Bitcoin network does not produce bitcoins. Bitcoin network like any transaction system produces transactions.

.Using your definition, I will agree that the "net cost" is $5.04.

There are some pretty far fetched numbers being thrown around in this thread. Thankfully we're in the speculation section
If we assume your 100k transactions per day are contained in 144 blocks mined, and also assume that the price per BTC is $250, and that the average power cost is $0.10 per kWh, and that the network is 350 PH/s and finally that power usage is 0.6kW per TH/s (which I believe is pretty optimistic, I'd push it more towards 0.75kW per TH/s)...
350,000 * 0.6 * 24 = $504,000 overall total cost to bang out those transactions, so a total cost of $5.04 per transaction.
However, you need to also include the rewards provided by the 25BTC generated per block as Phil pointed out.
25*144*250 = 900000. Divide that by the same 100k transactions and you get $9 earned per transaction.
So, in this speculation, each transaction nets $3.96 earnings.

Can I ask how you came to that number?
Because it is impossible to know that for sure.

Current hashrate is ~350,000,000 GH/s
https://bitcoinwisdom.com/bitcoin/difficulty
Let us assume that miners takes 600w for 1TH/s (some miners are better, some are worse)
So, the network runs as 350000 miners
Total daily electricity is 0.6 * 24 * 350000 = 5040000 kWh
1kWh costs $0.10
So, daily network expenses only for mining are $504k
OK, $504k is not equal to $1m but close enough
LOL!
No, it's not close enough.
It's half of a million.
That means that, according to your calculations, each transaction costs $5.04. ($504k / 100k)
Which is still a lot....
Even if you go wider with the estimate. It is not lower then $3 and most likely it is not higher then $8.
All 3 estimates $3, $5 or 8 per transaction are pretty high.
But op does not want to include the 25 coin subsidy. which is done about 144 times a day. so 25 x 144 x 257 = USD 925,200
I get the point that BTC will not work without the subsidy with current amounts of transactions. We would need a lot more of them for this to work once subsidy lowers.

Would be interesting to know how much has been spent on bitcoin mining. This is an amount that could potentially go towards the Epistemic Standard Economy.
There's articles about investments from VC in the bitcoin space, but there isn't much about the numbers being spent on mining. Probably not easy to get a concrete number with the network hashrate changing, factoring in that a top miner would have a high price the previous year for less Gh/s compared to the next, and several other things to consider.
If we were to go by this article http://www.datacenterknowledge.com/arch ... half-2014/ (from last July) it costs $1.5 – $2 million to deploy 1 petahash.
At the current network speed of ~300 Ph/s that figure would be around $450 million. (300 x 1.5)

It is probably quite a scary amount, I remember when I got into Bitcoin I tried mining both Bitcoin and Litecoin using my cpu, it's fair to say I mined nothing at all and quickly learned how it all worked
Yes.
Bitcoin network eats ~$1mln daily for processing ~100k transactions
So one transaction costs ~$10
Who pays this cost? Hodlers by devaluating their stakes.

they have spent round 1/10 of the market cap of bitcoin
They have spent much more. $1mln/day is the cost of electricity.
Do not forget the cost of hardware.
yeah i was talking about the mining investments not electricity, also because electricity isn't possible to calculate, because many countries have different rate
this days its even no worth to mine bitcoins
We were talking about hodling, not mining

basically with your estimate, they have spent round 1/10 of the market cap of bitcoin, if we take this in consideration, we can presume that if bitcoin rise it will always remain around 10%
unless the efficienty will rise faster than the price

10$ cost per transaction, do u mean the fee or how much the avergae is per transaction?
prime cost, net cost, first cost Yes.
