CUDA hasher
- CUDA client for nvidia cards
- Using the deepbit pool
Grab the client: http://www.bitcoin.org/smf/index.php?topic=2444.0
- Unpack
Execute from command line:
rpcminer-cuda.exe -url=deepbit.net:8332 -user=EMAIL -password=PASSWORD
- 40Mhashes/sec
Alternate CPU hasher
- Snarf a copy, use tarball for EL5 systems because the github clone will have problems with curl-devel's lack of AC macros
Run from CLI
./minerd --algo 4way --threads 6 --url http://deepbit.net:8332/ --user EMAIL --pass PASSWORD
- 4.2Mhashes/sec for six threads running on a 2-way xeon E5420 system
- 6.0Mhashes/sec if using the (default) 'c' algorithm
Trade market
Wish to use Mt Gox, but getting USD in there is a bitch. Attempting to use Liberty Reserve as it's an available injection vector, but you have to jump through more hoops to buy Liberty Reserve USD, which you can then pump into Mt Gox >_<
Looks like there's no way to do this quickly and easily...
Mt Gox
Mt Gox charges 0.65% commission on all transactions. This means if you want to buy some BTC with dollars, then convert back again, you want at least a minimum amount of nominal gain in value to avoid a real loss.
N coins @ X dollars per coin costs NxX dollars. Pay NxX dollars, you receive Nx(1-0.0065) coins. How much gain in value do you need to break even? 1 / ( (1-0.0065) * (1-0.0065) ) == 1.01312786 Call it ~1.3% Make it worth your time, the coin needs to appreciate by at least 1.4% to be worth it.
Example:
- I just bought at $27.05
- I need to sell at $27.43 or higher
