When will the Eth/Btc exchange rate stop declining?
First, you need to view ETH as an ordinary altcoin to analyze it correctly. Many people overestimate ETH, treating it as something equivalent to BTC, which is a mistake. Their track, valuation, and competitive advantages are different, so you can't force a binding exchange rate.
It was previously predicted that at the end of November to the beginning of December, BTC's market share might reach a peak close to 70%, at which point BTC's price could surpass 80,000 USDT. Therefore, it is also possible for the ETH/BTC exchange rate to drop to 0.03, after which altcoins may start to rebound and create chaos. Of course, ETH will also start to rise alongside other altcoins.
