Note: Before reading this article - this is not financial advice and I am not your financial advisor. Also it is only my point of view from my chart analysis.
I personally hold Ethereum and believes it can go very high soon. However there are some indicators that must be taken into consideration right now. Take a look at the Charts below.

The accumulated/distribution graph currently shows an uptrend, meaning that buyers are in control - i.e. a lot of people are buying. On the other hand look at the RSI it has touched the 70 mark - this is usually a sell indicator and a lot of traders might sell at this point. You might have already noticed that since this morning, ETH has lost around $100 in value.
The RSI indicator is usually an indicator for an exit point used by several traders. It may cross the 70 Mark a little bit but might fall back. However note that sometimes there are divergences in Market, this means that the price of the token does not reflect the trend of the RSI. Traders might be selling at this point and waiting a drop to buy more.
But for long term holders, I believe that it is not really a concern as the token will gradually go to a higher price very soon. In my opinion, ETH can go up to $6000 by end of December 2021 or close :)
