I think you misunderstood this. DeepSeek is considered to be very competitive hence why NVIDIA stock got wiped because traders believe it's overpriced, not necessarily because DeepSeek attacked the stock or something similar. If anything it's actually a positive development because they offer a better algorithm that makes AI development faster at a lower cost. I remember the CEO from DeepSeek also said they need more NVIDIA cards as a back-end to support their chat platform. CMIIW.
I wasn't too sure of what must have been the problem here, until I had to go digging out what truly transpired. It's quite funny though, but in summary, the deepseek looks more like a threat to some companies considering the fact that it doesn't consume much energy, and it is far efficient. So the competition should be between fellow AI companies like meta and Openai, and maybe energy companies as well. And most especially NVIDIA.
But from the look of things, IMO, it doesn't have a direct connection with Bitcoin mining or whatsoever, because I strongly believe that all mining companies aren't using the NVIDIA products. Though, sentiment will definitely come at some point, because the crypto community is very good at that.
