The cryptocurrency market can still be played, but the gameplay has completely changed.
Past cryptocurrency market: Just buy any random shitcoin and hold it to double your investment; during a bull market, even pigs can fly.
Current cryptocurrency market: Dominated by institutional funds (Bitcoin ETFs, listed companies hoarding coins, the rise of the RWA sector), market liquidity is concentrated in large-cap assets, small-cap coins exhibit more volatility, and it's become significantly harder for retail investors to make money.
