ETH is also doing very well at this point because it has reached a new ATH at its unit price so that it currently exceeds $ 3K for one unit, so in general ETH is also very good as an investment option in the long term.
If we are going to invest into etehreum right now, then probably you might be catching the topmost price as there are very less possibilities for etehreum to grow further from this current price levels. Because, ethereum is currently having huge competition in the crypto markets and its huge and senseless transaction fees is enforcing lots of projects to leave off it and to adopt many other new dapps platforms; BSC must be one of them.
