All the publicity about the "Bitcoin Bubble" over Christmas got me thinking.

Having discovered a piece of software called *very originally* "Bitcoin
Miner" free in the W10 app store I let it run for a few days and made
about 50p worth of bitcoin.

Next I discovered a free application called "Nicehash Miner", and
proffed a couple of decent graphics cards from the office. Now I'm
making £5.00 to £8.00 per day in exchange for 500 watts of electricity
(about £1.50 per day).

I feel myself being "reeled in" by this brave new world. Anybody else
got this problem?

I'm sure they're real.

The only practical option is to convert them back to pounds to spend,
not difficult but of course there is always the chance a bitcoin could
be worth £100k in the future. I'll hang on for now.

Really this is a bit of a "first world problem" It's only for fun and
technical interest.

Any graphics card worth using seems to consume 100-200 Watts.

Furthermore the it is a 3.3 volt supply that GPU's need, (the yellow
wires on your PC cable harness) so they require 30 amps or more! If
you're not careful with the wiring there is a very real risk of I
squared R's causing issues.

Just self indulgence, in my old age. Not risking much and it keeps me
out of the pub. The few quid I spend on electricity (maybe a tenner a
week at the moment) would otherwise be spent on beer.

I am utterly convinced that in 10 years time this will have evolved into
something completely globally transformational (and almost impossible
for anybody to regulate).

What you described above is the situation with bitcoin in the early days,
before the exchange rate started to climb.

At present there are around 1384 cryptocurrencies of which bitcoin is simply
the best known.

https://en.wikipedia.org/wiki/List_of_cryptocurrencies

If you check again I think you'll find you're generating one of the newer varieties.

Otherwise if something looks to good to be true - such as making £5-£8 (£50-80) per day
at a
cost of only £1.50 (£15) worth of electricity, while lying in bed or whatever - it
usually is.

Not quite. Look at https://www.nicehash.com/profitability-calculator/

I set up the experiment to validate the claim because I did not believe it.

I've actually been using 3 x nVidia GTX1060's which appear to generate
between 1.6 and 2.5 quid a day each (after charges) minus leccy cost no
more than 1.5 per day. Actually 400 watts consumption for this setup
with the monitor off!

Feeless transfer to coinbase.com wallet.

Certainly there is no loss going on based on the balances I see. But
you could regard this as a very elaborate fan heater in the limit.

Yes the difficulty factor increases every couple of weeks, to limit
supply to 1 block every 10 minutes and at the moment the reward is
12.5BTC per block (which halves every 4 years)

We must be about 80 percent of the way there.

Under 10m of the 22m coins have been mined so far.

Andy Burns wrote:

Perhaps I should say "changes" rather than "increases". At the moment
the worldwide horsepower dedicated to mining is increasing, so the
factor increases, if people were to shut down a sizeable number of
mining rigs then the difficulty will decrease to keep the rate athe same.

pamela wrote:

The total hash rate of all BTC miners is 22 quintillion hashes/sec this
week (up from 15 quintillion hashes/sec a month ago)

https://blockchain.info/charts/hash-rate?timespan=2years

1440 minutes/day = 144 blocks/day = 1800 coins/day = £14.5m/day

so Vortex's fractional share of that is
54,000,000 / 22,000,000,000,000,000,000
or 0.0000025 * £14.5m = 0.0003pence/day

That's why I can't see where the £5/day number comes from.

The heat could be supplied by the graphics cards, the electricity is being burned in a dumb heater to keep the place dry already. To him the cost would be the mining rig.
Any pitfalls I am not seeing.
The scheme yields pretty close to 9kw continuously.

That heater isn't on 24/7. It heats it up to 16 degrees then turns itself
off. When the temperature drops lower, it clicks back on again.

If you dump a constant 9kW into an enclosed space it'll get warm rather
rapidly. This is why server rooms are air conditioned.

If he can heat exchange into the river, then he might be onto something.
Though the fish probably won't like him for that.

Quantifying in £ is meaningless because of volatility. Could be £75 one

Did not play with graphics cards until 2nd week in January, and a
variable number of them since then....so can't give objective info on
income per card.

Nicehash actually mines with various currencies (automagically selected)
but pays out BTC.

Intention is to keep it stable for February and get a proper measure of
income versus energy usage. Also want to investigate the alleged
benefits of using a newer PC with SSD (which will no doubt involve a
whole day of fannying about) before that.

Of course it's all one bubble burst away from having been a pointless
exercise. Under no illusions here.

Quantifying in £ is meaningless because of volatility. Could be £75 one

Yes

Did not play with graphics cards until 2nd week in January, and a
variable number of them since then....so can't give objective info on
income per card.

Nicehash actually mines with various currencies (automagically selected)
but pays out BTC.

Just looked at the "profitability" they calculate for a single GTX1060
seems that using daggerhashimoto to mine ETH (ethereum) is what earns
£1.95/day [at an electricity cost of 63p/day] so then they convert that
to BTC (times 3 in your case) and that's what you're earning - not
direct BTC mining.

Fair enough, I'll worry if you report back that you've bought a room
full of Antminers :-)

Though the fish probably won't like him for that.

Actually, this will not heat the water: the power comes from the micro hydro, is
extracted, (slowing the river), and via various lossy generators etc., returned
to the river water as heat.

Wouldn't this energy have ended up as heat in the river water anyway?

The algorithm changes through the day. Neoscrypt and Equihash are the
main ones. Dagger Hashimoto less so.

No chance. Leave that to the Chinese and Russians.

And has mining become more efficient as my mate had a fairly big
mining rig (10 video cards or summat) but it was costing more in
electricity than he was mining at the time?

I know there is some fairly hefty number crunching required, hence
the use of multiple GPUs. Do you need GPUs or is mining something
that could run on an basic PC that is on 24/7 (acting as a server)
that spends most of it's time doing basically nothing except using
electricity. Obviously it's not going to yield very much but the
lecky will be used anyway.

I really don't understand the people who buy e.g. 10 GPUs at £400 to
£800 each, when for £4,000 they could buy an ASIC miner with 250,000
times the hash power of one GPU.

I don't understand people who buy ASIC miners either, but if you're
determined to be in the game ...

In this case it was because he (my mate) was just ahead of that game
and such products didn't exist.

Quite ... like coarse fishing ... or football ... ;-)
