As of September 2018, the highest Ethereum has ever been is $1,448. This is almost three times higher than the current price of $488. While this may seem like a huge difference, it is important to remember that Ethereum is still a fairly new currency.
It was only released in 2015, and it has only been traded on exchanges for about two years. This means that the market for Ethereum is still relatively small and volatile.
The reason that Ethereum reached such a high price in September 2018 was due to a number of factors. First, there was a lot of positive news surrounding Ethereum at that time.
For example, Microsoft had just announced plans to launch an Ethereum-based blockchain product. This generated a lot of excitement among investors and caused the price of Ethereum to surge.
Another factor that contributed to the high price of Ethereum in September 2018 was the launch of a new cryptocurrency exchange called Binance. Binance allowed users to trade a variety of different cryptocurrencies, including Ethereum.
This helped to increase the demand for Ethereum and caused the price to rise further.
Finally, September 2018 was also the month when China announced plans to ban cryptocurrency trading. This caused a lot of investors to sell their Bitcoin and other cryptocurrencies and move into Ethereum because they believed it would be less affected by the Chinese ban.
All of these factors combined to push the price of Ethereum to its all-time high of $1,448 in September 2018. However, since then, the price has fallen back down to around $500 as investor interest has cooled off.
