i think when we look at the place of ETH rightnow, we can easily see ETH is at the second place just after BTC, so it is obviously that ETH is still one of the most useful altcoins worthy to invest rightnow and surely in next few years ETH will still be a great altcoins for both long term and short term traders.
trust in Eth is still very high and it is natural that they are in the best position for altcoins. When viewed from a long-term proportion, it is still very good, but for the average price it still seems stable even though it has increased, Eth developers seem to focus more on efficiency of use this year and maintain market volume
