According to @StockMarketNerd, 12 late-cycle warning signs now visible include obsession with year-to-date return charts, “investing is easy” narratives, questioning Berkshire’s relevance, normalization of 20x sales multiples, tolerance for pre-revenue business models, $10B+ firms with weak HQs and no scalability, trading equity rights for revenue, loss-making companies signing $300B commitments, the return of SPAC promoters, far-out stretch targets to justify prices, constant capital raising with insider selling, and hostility toward skeptics (Source: @StockMarketNerd on X, Oct 6, 2025 https://twitter.com/StockMarketNerd/status/1975220593231335532). Traders can translate this checklist into risk controls by scrutinizing high-multiple and pre-profit names, monitoring insider activity and capital raises, and being cautious of story-driven deals—an approach that also helps crypto participants evaluate froth in token sales and revenue-less narratives (Source: @StockMarketNerd on X, Oct 6, 2025 https://twitter.com/twitter.com/StockMarketNerd/status/1975220593231335532).

According to Bobby Ong, several historical signals can suggest that the crypto bull market is nearing its peak. These include increased retail interest, such as barbers and Uber drivers discussing whether XRP or Cardano is a good buy, the rise of speculative talk about potential 100x altcoins, Coinbase reaching the #1 spot on the App Store, and celebrity involvement in cryptocurrency promotion. Traders should monitor these patterns as potential indicators for market cycle tops, which may impact short-term and long-term trading strategies for major cryptocurrencies and altcoins (source: Bobby Ong).

According to @AltcoinGordon, current Bitcoin (BTC) price action shows a strong upward movement with minimal participation from retail investors, as evidenced by low retail trading volume (source: Twitter/@AltcoinGordon, May 19, 2025). Historically, retail traders often enter late in bull runs, which can indicate a potential market top and a profitable exit point for early investors. Crypto traders should monitor retail inflows and sentiment closely for signs of trend reversal and optimize their strategies for profit-taking during surges, as institutional activity currently drives the market.
