At op. most people fuck up by rushing in and buying too much gear.
lets us say you build a 3 card 3080 rig. you got good prices and paid about 2600usd to build the rig.
it does 270mh which is about 19 a day
it burns 700 watts which is about 2.50 a day at 15 cent power.
you are netting 16.50 a day
______________________________________________________________________________
soooo 2600/16.50 = 158 days.. paid the gear off. Seems like building 2 or 3 or 4 rigs works.
maybe it does or maybe it does not if there is a crash.

build 1 rig and hold 2600 cash on the Side for the second rig.
and mine if there is a crash even if you mine at a small loss. WTF?
this is mine and hold. And can garner big profit.

you need to weigh both methods above.
Pedal to the metal full speed ahead vs slow and steady wins the race.
I dance between the two.
I study a lot of ratios.
coin price
coin difficulty
my cash on hand
my gear on hand
my debt
my coins on hand
I juggle all that.
Here is a method that can help.
sell off used gear at good prices
look at ebay right now.
https://www.ebay.com/sch/i.html?_from=R40&_nkw=s9%20hashboard&_sacat=0&rt=nc&_udlo=75&_udhi=200look who is selling the cheapest used working s9 hashboards. Me
way better than anyone else. Why is that? because I held spare parts. hoping for coins to go up in price. thus spare parts go up in price.
So rushing in to build can be a bad move. or not. It is what makes this fun.
