The core contradiction in the crypto world in recent years has been the clash between Bitcoin and altcoins, as well as the continuous rise of Bitcoin's dominant position (known as "big cake bloodsucking"). In fact, for secondary traders Understanding the contradiction and capital flow patterns between BTC and altcoins can help you avoid getting caught up in the macro and crypto noise vortex. first, BTC is regarded as digital gold and a representative of value storage Shanzhai coins are often seen as speculative objects born with narratives. The contradiction between the two: BTC's' Value Storage 'vs. Alt's' Disruptive Applications/High Growth Potential'. The limited total market funds are allocated between BTC and numerous Altcoins. In a bull market, funds pursue high returns and flow into Alts; In a bear market or volatile market, funds seek stable returns to BTC or stablecoins. The entire encryption cycle is in two capital flow modes: Capital flow mode 1: BTC → Alts usually occur at the beginning or middle of a bull market, with optimistic market sentiment. Investors allocate some BTC profits or newly added funds to counterfeit coins in search of higher beta returns. Capital flow mode 2: Alts → BTC/Stablecoins When the market turns bearish, risk events occur, or the counterfeit currency foam is too high, funds will withdraw from the counterfeit market. Part of it flows back to relatively stable BTC, while the other part is exchanged for stablecoins (such as USDT, USDC) for safe haven observation. Combined, it forms a complete bull market capital cycle: fiat currency → BTC/ETH/stablecoin (deposit channel) → hotspot Alts (chasing hotspots) → profit/safe haven → BTC/stablecoin → fiat currency (withdrawal) or waiting for the next opportunity. Therefore, it is much easier to judge the trend of the altcoin market than to judge the trend of Bitcoin. The breakthrough of BTC often boosts the confidence of the entire altcoin market. You can formulate a strategy for altcoin speculation after the trend of Bitcoin is determined, and exchange altcoins for U or Bitcoin after reasonable profits.
