But that's just with 2 GPU's! Any larger bitcoin miner has a few hundred (up to many more) of these graphics cards running. 100 GPUs would require only 20 days! Any larger entity could easily setup 1000 GPUs which cuts it down to 2 days, etc.
Probably there will be password cracking pools, similar to altcoin mining pools, which pay for your GPU resources in bitcoins.
- crisnoble 14y agoThey will need to do something with their rigs once mining gets too hard and the payouts too small.
- aidenn0 14y agoHmm, what's the opportunity cost (in terms of average BTC not mined) for doing 2^48 attempts?
- shawabawa3 14y agoIt takes on average 2^54 hashes to discover a block at the current difficulty. So 2^48 attempts is 2^-6 (1.5%) of a block on average. A block is currently worth ~$2000, so 1.5% of that is ~$30
