Hello budget miners! I figured we could source valid
profitable cheap entry-level mining ideas and equipment and processes in one post.
I will keep this updated to the best of my ability with suggestions and postings in the
Bitcoin > Mining board.
Graphics card Mining
It's a good start for a 1 GPU mining rig, you won't make a lot but its something you can run at home with multiple algorithm options leave it a good long term option as well as your operation grows.
Your looking at about $1.00-$3.00 a day this route depending on your Graphics card, minus the electricity cost. A 2080ti opens many algorithm options.
Here some profit calculators that are easy to use Nicehash profit calculator or check out WhatToMine profit calculator.
You can generally build a really cheap rig with old Dell Optiplex 790 systems or like-minded end of life systems. And a PCIe to x4 USB PCIe adapter just make sure its pcie usb and not a usb 3.0 adapter. these open up expansion opportunities on your low end board for around $20-$30.
If you dont have a powerful PSU try out separate ones with the cards and risers running on the same power supply with a power supply tester or a PSU bridge ($4)
Its a temporary solution but will get you by until you can find a deal on something of better quality.
Currently Not profitableHelium MiningHelium mining is another way and probably the most profitable as far as equipment cost goes, 1k should get you a nice top of the line setup, A lorawan helium router $450-700 on ebay right now (bobcats are the best from what I hear, but avoid sensecap and syncrobit) , antenna (5.8dbi or 8dbi) lmr400 cable , copper rod, lightning arrestor, 4ft satellite mast, cat8 and some awg10 wire for your lightning arrest system.
If your lucky and have a rohn tower at your house you can make about 50% more then the network average putting it 10+ft above your roofline. every foot of LMR-400 cable degrades your signal about 0.04 DBI
(so a 30' cable =1.2DB strength degrade so turns a 5.8dbi antenna into a 4.6 dbi antenna essentially)
I make about $4-$7 a day on a helium router 35' in the air on a 5.8 dbi antenna. The wonderful thing about them is they only use about $1 in electricity a month.
If you go this route dont shy away from moving the antenna outside , before I put mine outside I ran it in a window and made like $30 a month,
My helium router outperforms all my other gear profit to cost wise. The crappy thing about them is you can only really run one profitably at home but if you have friends that would let you install one around town you can make a killing! (just check helium maps and dont install too close to other helium routers or your profits will go down, they can measure signal RSSI strength and if its too strong they can tell your too close to another unit/s.

I believe in
BTC all these little methods such as eth mining and hnt mining are just ways to get more BTC much more efficiently. Also considering 90% of BTC is mined up already I personally feel that entering the asic game right now is a fopaux. It seems like every other day I read about a new 100-500MW asic mining operation opening, I can make the same as any asic with much less electricity and less purchasing cost, and I can run at home. (remember shipping to a datacenter is a longer roi since it adds to overall investment cost especially if your insuring your investment)
