According to Flood (@ThinkingUSD), the mainstream adoption of cryptocurrencies follows a clear roadmap: initial integration with wallets, followed by listings on Tier 3 and Tier 2 exchanges, and eventually Tier 1 exchanges before achieving global reach. For traders, recognizing these stages is crucial as token listings on higher-tier exchanges often trigger significant price movements and increased liquidity. Monitoring wallet adoption and exchange rollout can provide early trading signals and strategic entry points (source: Flood via Twitter, June 4, 2025).
