Possible disadvantages

  • Service Fees
    Upwork charges both freelancers and clients service fees, which can add up to a significant amount, especially for larger projects.
  • Competition for Freelancers
    Due to the large number of freelancers, competition can be fierce which might make it difficult for new freelancers to get noticed.
  • Quality Control
    While Upwork has a large talent pool, the skill level of freelancers can vary widely, requiring clients to spend time vetting candidates.
  • Platform Dependence
    Both clients and freelancers might develop dependence on the platform, making it risky if Upwork changes its policies or fee structure.
  • Limited Direct Contact Information
    Upwork restricts the initial sharing of direct contact information to avoid working outside the platform, which can complicate preliminary discussions.
  • Potential for Miscommunication
    Despite available communication tools, remote work inherently carries a risk of miscommunication due to different time zones and cultural differences.
  • Live order book mirror
    Real Polymarket prices, refreshed continuously. Your simulated trades fill at the actual market price, with realistic slippage modeled in.
