The proportion of market value of altcoins, although Bitcoin has maintained a high volatility in the short term since its release on April 9th, has been on the rise overall. However, the proportion of the altcoin market has not shown an upward trend, and has further declined compared to April 9th. As for the current situation, Bitcoin remains at a high level and oscillates below the neck line, and there is no main narrative for altcoins to emerge. In this context, it is expected that the market share of altcoins will not have any outstanding performance in the short term, and even further decline will occur with the volatility of Bitcoin. altcoins can only maintain a local opportunity situation. But with the emergence of a new bull market trend for Bitcoin in the second half of the year, I believe the altcoin market will also see a positive growth trend towards the end of the year.
