If Ethereum successfully breaks through the long - term downtrend line and holds the key support level, it may experience an uptrend. Possible scenarios include a steady price increase as more investors gain confidence, leading to a rise in market capitalization. It may also attract more developers to build on the Ethereum network, further strengthening its ecosystem. Investors should closely monitor market sentiment, trading volume, and any new developments in the Ethereum 2.0 upgrade while considering their investment strategies.
