So basicly i will be buying 6 antminer s7 batch 8

so total has rate should be about 28+ Th/s

what are my chance on finding a block within 30 days ?

or am i better off just mining on a pool  i really like Minergate so if i mine in a pool it would probably be on that pool the   fee is 2.5% on bitcoin.



 any help will be apreciated , maybe even with a donation once i get up and running.

please excuse my english its not exacly my best trait.

You are much better off with a pool.  With electricity and miner cost most cannot solo mine at that amount of gear.   Even though it seems big for a home to have that, it's pretty small in the overall hashrate.

So go pool mining is my advice.

If my calculations are correct, you have a little over 25% chance of finding a block on the next 30 days with 28 THs but if you use it in a pool you could easily earn 6.5BTC monthly with the current difficulty so If I were you, I would go still with mining in a pool rather than taking a lottery road

if the diff do not increase you should find a block in a 120 days average, but the diff will increase so the chances are much higher

with double or x3 of that power i would try solo, otherwise it's better to go with a pool

 Pretty much zero as you likely won't have the miners within those 30 days from when you posted.


 As to your real question, your chance of achieving a block solo-mining with that kind of hash rate is very very low.
 You would almost definitely be better off going with P2Pool or going with one of the major pools.

You can very easily calculate how long it would take you to find a block knowing the hash rate and network difficulty.  The formula (at least the simplified version) is:
6 S7s (batch 8) gets you 28.38TH/s.  Current difficulty is 65848255179.  If you had those miners right now, we can see that it would take you:
So, 115.34 days to solve a block.  Therefore, you've got about a 26.01% chance of finding a block in 30 days with that hash rate ... assuming it was mining right now.  As soon as the difficulty changes, that value changes as well.
