Do you push or drag flux core?
Excuse me, as a seasoned professional in the realm of cryptocurrency and finance, I'm genuinely curious to understand a phrase I came across recently. Could you please elaborate on the question, "Do you push or drag flux core?" I'm not entirely sure how this relates to our field, but it seems to be a technical term in some other industry. Perhaps it's a reference to welding techniques? If so, I'd appreciate a brief explanation of the difference between "pushing" and "dragging" flux core, and how this might relate, if at all, to our discussions in cryptocurrency and finance. Thank you for your time and patience in clarifying this matter.
