I have an Antminer s7 batch 9 running at 7.4th/s. Will it be more profitable mining in a pool or just by myself?

If you solo mine, you get big rewards, but have very low chances of getting it. If you pool mine, you get constant payout but it is very low. Take your pick.

7th/s is about a 100,000th of the total network. 

This means over a month you have only about a 4% chance of finding a block (30*24*6/100,000).  Your changes will fall in the future months as the difficult rises.

So "‘You've got to ask yourself one question. Do I feel lucky?"

And the chances are only going to get worse.  If you really want to lotto mine I suggest getting a compac or two and a RPI.   You can mine for lotto for fun if you want to.

S7 for most is to big of gamble the machine is pricey for a payday that likely will not come.  And there is also electricity cost so your cost will get more and more.  I would highly suggest a pool.

i would not do it anymore, the chances are too low, and the halving is incoming, so in th best case you are solo mining for 12 btc if it will ever happen

with that hashpower you can point at any pool and do 1 btc per month easily, which would be roughly the same earning before the halving

Can you please show the math that "easily produces" 1 BTC/month? My simple use of the bitcoinwisdom calculator indicates it's much closer .625, and that's assuming a zero difficulty change during that month.

While if you want to round to the nearest whole BTC, then I guess that .625 rounds WAY up to 1.

well the OP said that you has 7.4 tera, and this is 0.032 per day, which is around 1 btc per month

I thought an S7 produces about 4.7 TH/S, not 7.4 TH/S as OP's. Unless OP got a magical S7...

I would bet it's a "digit transposition" as opposed to a "Magical S7". I didn't look at hist quoted rate, and just couldn't see a "non magical" S7 doing 1BTC per month (before running expenses).

That is kinda the key is it's before expenses.  So every person will be different chances are on profit.   But it is possible some bought S7 at 350'ish if they used fiat they got a decent deal as far as miners go currently.

But I would agree it was a typing mistake on 7.4 .  Easy to do when it's just 2 digit's and typing fast.

it was also strange when i see it, butmaybe he had two of them underclocked, one never know, it could be at 3.7 each they may work better an dconsume less, if you have a hot room or something

Highest profit would PROBABLY be running your own P2Pool node and merge mining with it.

Solo is a VERY high risk with very low probability of any return at all, though *IF* you did manage to find a block it would definitely pay for your setup.
Just not very likely to find that block with such a low % of the total hashrate.

Solo mining is not good option when the difficulty rises fast like now. You might not find a block for long time.
