Ethereum Classic for me will be affected somehow by the upcoming "The Merge". If there will be no hard fork will happen on the Ethereum chain, then I think there will be some miners who will try to mine Ethereum Classic. We still don't know what will happen after "The Merge", this will be one of the biggest events in the cryptocurrency world.
If no fork for PoW coin from ETH, most of ETH miners will switch to mine ETC. If there is a PoW coins from ETH, there will be less miners switching to ETC. However, whatever happens with the Merge, if it moves to PoS successfully, ETC network will receive more hashrates from miners.
If in 2020 bull run, ETC can rise to $200, it will rise to higher price in 2024 or 2025. Especially if in future, there is no PoW for ETH.
Overall, Ethereum Classic will stay for me.
One of strongest Proof of Work coins. Ethereum Classic will stay here. If you look at ETC chart, there are good waves for this coin.
