I don't think about when the bullrun period will come and end the bearish market but I really hope bullrun can come soon in the near future because it's been too long for us all to survive the current market conditions.
Price movements that continue to fluctuate and change suddenly in my opinion are very difficult to predict. if you want to buy it better when the market conditions are red, I think it's the best solution now and last for the long term or until prices have risen again to sell and take profit
Those people or new come investors who still worrying about this questions - are losing money every day! Ethereum is the most stable coin!
I think you can buy ETH at the moment if you want. It's the best altcoin all the time and I think this downward trend can't kill this altcoin although I know that ETH is really old right now.
