not worth the investment unless you can go very big, it's centralized as it get and not casual anymore
for example 1 single s9 net you less than 0.01 per day with 1.4kw/h of consumption, and the diff keep increase, which mean this amount is decreasing over time
we are already approaching the day where you need the whole resitendial power(usually here 3kw/h) to run a miner...
Just plug the numbers into a mining calculator, you'll find that unless you have ridiculous electricity rates, you can make profit. Electricity is 0.10 $/kWh where i live and I could easily turn a nice profit off 5-10 S9's.
as i said in that post you need to invest big to make somethign significant, 10 s9 is $20k, not everyone has 20k ready to throw at crypto
and with 10 of them you are only generating 0.08 a day, minus electricity, it's not that much....
I plan on starting with four S9s which with a 10c power rate will net me about $700 per month after power costs. Factoring in the resale value of the miners, that's extremely profitable. In the real world of investing with stocks and real estate, you couldn't even dream of returns like those.
it's not about how much it net you, it's about roi , those thing will recover their initial investment? with the diff that keep increase? also isn't more wise to invest in x11 asic they consume 1/7 cost the same and earn you a bit more
Well the net profit and return on investment are pretty directly linked - you can't just invest next to nothing and expect to get a decent ROI.
I'd say that the key factors of whether mining is profitable or not are:
1. Your electricity costs. Unfortunately, if you only have a small amount of money and are looking for 1-3 miners, you probably won't make any profit unless you are lucky enough to live in an area with cheap electricity. Sometimes electricity costs can even exceed the revenue from your miners. The only solution to this, if you're in it for the long run, is
solar power but this will add a new level of risk to your mining.
2. Where you get your miners. Bitmain is capable of being so profitable because not only do they sell miners, they own thousands of them and mine themselves. Obviously you can't do this, but you
can buy second hand and use other ways of attempting to get cheap miners.
3. Future difficulty. In this case, you're at a fairly good point because you know that your profits will remain not consistent but
nearly consistent for the next four years until the next halving.
In any case, mining is a risky venture and doing it on too small a budget, especially in an area with high electricity costs, is probably not a good idea.
