Whether it's worth continuing to invest depends on whether you can build a 'relationship that cannot be replicated'. The core thesis is: capital-driven imitators can quickly replicate products, but they cannot replicate the trust you've accumulated with customers, your service network, and your deep industry understanding. If your competitive advantage is built only on 'products', it's indeed fragile; but if it's built on 'how well you understand this customer', the barriers are completely different. Specifically, things worth doing include: systematically organizing the cases you've served, showing customers what platform purchasing cannot solve that you can help with, and ensuring every quotation and transaction condition has clear written records, letting customers feel your professionalism and reliability. The true value of a distributor was never 'moving goods over', but 'giving both buyers and sellers peace of mind'.
