1. Yes, if you setup your own node, and you get a complete solo mining operation up and running, you would increase your privacy... Nobody would know you were the one that solved the block. Other nodes would just receive the block you relay to them, but they would have no way of really knowing you were the one that solved it in the first place. If you mine in a pool, the pool operator will always know how much he has payed out, to which address, which username, which ip,... this is not the case if you do a completely solo mining operation.

2. I doubt it... Depending on the VPN... But i don't think it'll do you much harm. There might be some latency, maybe even some package loss (in extreme cases), but in a pool mining setup i don't think this will really influence your income.

3. If you setup your own solo mining operation, you might want to have decent connectivity to other nodes... You'll have to download a new block and verify it before you can start mining, if this process takes to long, you'll lose some valuable seconds each time a new block is found by someone else. In a pool mining setup you get your work from the pool, and you don't need to download the complete block (you're not running your own node, at least not for mining purposes) so this is less of an issue.

Now, just as a sidenote... I don't know if you were kidding about the loan for an rPi4... You do know an ASIC is expensive to buy AND to operate, right? If you pay to much for you electricity, you might always mine at a loss even if you have a "perfect" setup.

Also, setting up a solo mining operation isn't plug and play... It requires some knowledge and preferably reliable (redundant) hardware.

And last but not least: you know that it's all about odds and averages if you solo mine, right? You might mine forever and never get *any* income... If you mine in a bigger pool, it'll cost you some privacy and a % of your income, but you'll have a steady income and you'll know you're not in charge of setting up and maintaining your complete operation (just your network connectivity, your home power and your ASIC)

Is the unlimited rate of $119 is a monthly basis?
If yes then you can save more compared to the fixed rate since you said it's $160/month?

The question is if the unlimited rate has a wattage limit? I mean how many miners you can able to run at $119 unlimited rates?

One s19/pro can consume around $160 every month for a $0.065 rate so if choose the unlimited rate you can save more but the problem is if your miner can run stable.

Both of them have pros and cons it's your choice if you know that your miner can run stable then choose unlimited but if not I guess fixed rate would be your last choice.

If you're looking at that S19 at $3200, don't do it!
If you have 5c/kwh you're going to ROI in about 3 years while the S19 H next to it has 600days at the same electricity rates and even that it's not the best deal on the market.

I am looking at the Bitmain S19 Pro (110). Seen some new ones for around $3500.
Is the S19 H the Hydro 198TH for around $11K ?


The price goes up when the revenue per THs goes up and they come crashing down to somewhat real manufacturing costs when the gold rush is over and ROI numbers are counted as above in years. For example from July to December last year the revenue per TH/s stayed mostly above 30 cents, peaking at 40, that's 40$ a day for an S19, now its 7cents per TH/s, 7$ a day, a difference of 30$ a day or 10k a year, so the price of the gear was matching the demand of people rushing in dreaming of those profits lasting forever.


Then $500, then $200 or $100, because...reasons!
