he problem with solo mining and pool mining is that pool mining requests your username via stratum and then compensate you on the BTC address which is associated with username . which means if you could pass in your wallet address , you're all done!!
Not sure I understand what you are trying to say here.
the main reason for this mini pool is that my friends and i can mine on our own, our hashing power combined is well over 2.5 Ph/s
While 2.5PH is more than good enough hashrate for an individual or a few people, it's just a drop in the ocean as far as mining is concerned, your chances to hit a block are
Chance per block: 1 in 59,307
Chance per day: 1 in 412
Time estimate: 1 years
http://solochance.com/This is more like gambling, to be honest.
is there any way i can pass in my --BTC-address from my s19 to bfgminer as a stratum-port ?
No! ... Not before someone "hacks" those S19s.
