Topic: Bitcoin Mining with a Six-Figure Budget (Read 852 times)

Phil was very very nice to go through that to say the least.   OP just is putting out numbers and asking if it's profitable without any research.  I took a look though his post history and on May 27 less then a week earlier he was wanting to know about spending 100k to invest in making a bitcoin game - https://bitcointalksearch.org/topic/m.14992100

"Hi,

Is 100k USD enough to start a nice bitcoin game with a nice bankroll? I am not a programmer so I would need to hire a team.

What do you guys think?"

Needless to say he locked it and did not invest.  This thread likely is another one without OP investing.  

Okay  I will pretend the op is completely legit.


Mining btc is kind of a high rate / yield junk bond.

So after a year  if it does not fail  you could get 240,000 back.  A 20 % profit.

An s-9  is 2100 usd
A power supply is 140 usd  so 2240 usd

shipping is 100 usd

so 2340 usd. 

take 200,000 divide and  80 of them = 187,200

this will use 80 x 1400 =  112 kwatts per hour   2688 kwatts per day  80,640 kwatts per month

hot as fuck well hotter. 
so a cooling system needed.
a build needed.
the internet needed.
3 workers needed.  maybe 4.  to cover the place 24/7/365


what will it earn.

if you had 1120th running right now at this moment it would earn 1587 usd today for the 1 day.

but that does not count power  about 135 usd a ay if you have 5 cent a kwatt power

so 1587 - 135 =  1452  daily profit  take away 3 days pay since you need workers 24/7  so lets say you are in a cheap labor country

so the 1452 - 52 = 1400 a day.   you rent the building  you cool the building say 100 a day.

so right now  1400- 100 = 1300 a day.


the future the truth is no one knows  we guess.
the next difficulty  is look to be the same  as this one.

the next difficulty is 3 days away.

so from right now this moment in time  take the 1300 x  16 = 20,800  back against the 188000 you spent

so you would be 160,000 in the hole  at next difficulty jump  if you started today  right now.

next difficulty jump   % jump I do not know

coin  price I do not know

so you are in the world of who the fuck knows.

on about june 18

on about july 2  the ½ ing comes  and the mining reward drops from 25 to 12.5  and the real fun begins.

So  for a good answer to your question  it is : I don't know do you feel lucky?

It is always easier to buy than mine.

Most of these are not serious  I mentioned this in a previous one in Mining board.   It tends to be people that think mining is a get rich quick scheme (which it is not) and come with a number very high for them thinking it means more profit.    They do the ROI and find out it is not get rich quick... and tend to leave thread.  If he posts electricity price we can give a idea if chance of ROI, but never invest more then you can lose.

I highly suggest OP starting off slow or anyone for that matter.  To jump in with 200k worth of gear from 0 would be crazy. If he is serious about starting mining I would suggest finding a place (hopefully he can start at home or place he already has access to).   And get a miner or two to learn with. 

And no offense was meant OP.  Its just when you ask some of the questions you did it is not in line with someone ready to invest 200k, or even 20k. 

 If you have to come here to pose such questions, I don't believe you to be serious.
Look here and check to see if these latest miners are profitable now.  Then read this to see how other companies are faring.  After that, check out this bitcoin halving clock to find out when the amount you will mine gets cut in half.  Maybe you can cut a deal with the KNC bankruptcy trustee to buy their miners cheaply and have them shipped to you but I would be careful, once they begin selling miners again, they will probably fill their datorhall first (since old habits die hard) and then ship to you... it could be 6 months and many excuses later before you receive them.

You are missing so much.   You need to know your electricity cost, your equipment (cooling, psu's, etc).   Each can very depending on location and that brings up cost of location.  But unless you are hosting somewhere you have a lot to figure out.  And giving you ROI months out.... no one can tell you accurately especially missing so much info.

It's going to be highly tied to electricity price.  But most will be looking at S9 that are buying new gear due to specs.

Hi,

I want to build a mining operation in a low-electricity country. I have USD 200,000 ready to invest.

What are some good machines to use? Is it worth the money today?

How much ROI can I get monthly approximately?

Thanks
