Crypto Market Concentration
Bitcoin alone accounts for ~50% of total crypto market cap. Top 10 coins account for ~80%. The ‘long tail’ of 25,000+ smaller coins makes up the rest.
Stablecoins (USDT, USDC) sit at the top because they peg to the dollar. Their market cap reflects total dollar reserves backing them.
Volatility is extreme. Bitcoin alone has swung 80% within a year multiple times. Long-term hold strategy (‘HODL’) has outperformed most active trading approaches.
