These scenarios are not guarantees. They show the most likely path, the upside path, and the downside path based on the evidence available now.
The most likely path, plus upside and downside
Regulatory pressure on crypto exchanges increases, leading to a temporary contraction in trading volumes as operators prioritize compliance over growth.
Increased investment in security technologies leads to a stronger, more resilient crypto market with enhanced consumer confidence.
Continued compromises and lack of regulatory clarity hinder the industry's growth prospects, leading to significant market pullbacks and loss of trust.
