Re: [Guide] Solo mine testnet bitcoins with bfgminer, Bitcoin Core, and a CPU/GPU
After almost 4 days, i managed to mine 4 blocks. But due to relative slow internet connection, 2 of them become stale. Overall it's good experience and i got about ~0.05 tBTC, which probably will be used to try few different OPCODES on scripting or simply donate it to tBTC faucet.
On a side note, on 3rd day i tried to mine only with 1 thread CPU since the goal to mine block with difficulty 1. But when i shutdown my PC, i got this error message with >100K occurrence. Quick search on google shows it's due continuous CPU usage for long time, although i'm not 100% sure it's due to bfgminer.
Did you monitor your CPU miner a bit? I just catched an instance where the last block was 20 minutes ago and bfgminer never adjusted the difficulty setting from its '125M' value. Does it take a bit longer to adjust or what is the cause? Or is it just not reflected in the user interface? I'd have expected it to drop to 1 as soon as the 20 minute mark passed, even if it may not end up being first at submitting something to the network. But it simply didn't budge.On a side note, on 3rd day i tried to mine only with 1 thread CPU since the goal to mine block with difficulty 1.
