Hello, as far as the alt coins go, i seem to only be able to get some mined coins when it first starts, once more then say 25 workers mine, i get next to nothing, lol.... i been on bilcoin for 4 days now and am up to 1300 coins.... but then i see some new coins come out and people are making 100k first day, and such

What would be a good min hashrate for alt coins? i can get up to 1mh right now, but am wanting to add another card, and hopfully get up to almost 2mh.... or just build a new rig with 3 280s
