Good program, solid work.
I placed several addresses randomly in a database, specified a keyspace somewhere nearby and got a hit on every single one - 100% reliable.
Using a RTX 2080 with -b 224 -t 256 -p 1024 (compressed) gives me 820MKey/s with up to 50k addresses, and 370MKey/s at a 400k database.
Well, the MKey/s counter is bugged, it doesn't match the elapsed in the "--continue FILE", which doesn't match with the overall progress, but that's not a problem at all.
has anyone been able to get bitcoin from this method?
NOPE. And i am damn sure that i am not speaking just for myself, because the possibility is like winning the lottery 50 times in a row. Get a calculator and find out for yourself.
But it is interesting, as a hobby, and you can replace the database with whatever you like, so, maybe it's useful someday.
