Born only a few years ago in 2015, Ethereum has grown into an established blockchain with an even more established native coin. Some might think it's all just hype, but the chart we've prepared here says otherwise — it displays Ethereum's dominance over the whole crypto market (the ratio of ETH market cap to the cumulative crypto market cap). If the line goes up, ETH is rising in value against other coins, and it might be a sign for you to reconsider your portfolio decisions. If it goes down, well, up to you what to do with that.
