Did a bitcoin miner solve a block alone?
I'm curious, was a single Bitcoin miner able to solve a block by themselves, or was it a collaborative effort involving multiple miners? With the nature of mining being so competitive, it's interesting to understand the dynamics of how blocks are actually solved in the network. Do miners often work in pools to increase their chances of finding a block, or are there instances where an individual miner is able to pull it off all by themselves? I'd love to hear your thoughts on this topic.
Can a solo bitcoin miner solve a block with an AntMiner S9 rig?
Could you elaborate on the feasibility of a solo Bitcoin miner utilizing an AntMiner S9 rig to successfully solve a block on the Bitcoin network? Given the current mining difficulty, hash rate requirements, and the competitive nature of Bitcoin mining, does the AntMiner S9 possess the necessary capabilities to find a valid block solution independently? Additionally, what factors should a solo miner consider when evaluating the profitability and sustainability of such an operation?
