Do you think ETH may outperform BTC in the next bull run?
no . It's very impossible because the potential of bitcoin is good than ethereum and in fact Eth can make progress only when bitcoin gradually increasing like what always happened also in some alternative coin in the market which very affected on bitcoin growth .so its very difficult for ethereum to overtake bitcoin. Actually some ppl nowadays start lossing interest with it because of being so stagnant so it's impossible IMO .
well, even though it looks the same, I think bitcoin is indeed much more sought after, and is needed than ETH. although most of me see that ETH use is often used in investment, but the value is quite cheap. however, these two coins have great potential, only if compared, of course people prefer bitcoin.
