DePIN sector mindshare has plummeted to a one-year low of 0.87%, down 57.50% over the last year, indicating waning investor interest. Tokens like Helium and Hivemapper are down 95% from highs with low daily trading volumes, suggesting significant downside risk for these specific crypto assets despite potential underlying business strength. Investors should be cautious about token utility post-bootstrapping phase and consider the declining mindshare as a bearish signal for the sector.
