You can buy Ether, and in my opinion Ether's potential is still quite good. But I would recommend you to make a portfolio investment. Don't just buy Ether currency, you can also buy some bitcoin or other air coins. This way you won't be stuck in your own money because of a currency. In fact, at present, there is a large degree of speculation in the currency price and it is controlled by some giant whales. At present, the market for the entire cryptocurrency is generally lower. Although you can't predict the long-term trend of the currency, as long as you keep an eye on the news of the currency, it is easy to see when the currency will have a short-term rebound. For example, the ETF review submitted by the BTC last time attracted a wave of attention. The price of the coin also broke from ¥7000 to ¥8000, but it quickly fell back to the price of six or seven thousand. In addition, the rebound of bitcoin prices in recent days seems to have a certain relationship with the frequent transfer of Bitcoin's richest address. In short, investing in cryptocurrencies is a high-risk, high-reward, purchase cautious, and has a high sense of the market, making quick buy and sell judgments.
