Ethereum can be the next real store of value, but people still prefer to use bitcoin than ethereum. The ethereum price is more volatile than bitcoin because ethereum follows behind bitcoin so when bitcoin is down like what we saw, ethereum and the other coin will just follow. Many altcoins follow to go down and it is waiting for bitcoin price increase again so the altcoin will also follow increase.
that's what mostly happens in the crypto market. Bitcoin's dominance is still unbeaten and that causes bitcoin price movements to affect the overall crypto market conditions. including ethereum assets.
ethereum has grown to be a great asset. it is natural for everyone to speculate highly on the future of this asset. but to align with the functional bitcoin of course everyone will still choose bitcoin no matter what.
People who do not believe in bitcoin will see that bitcoin can back to the higher price anytime and bitcoin still be the best investment so ethereum will be the second investment. Ethereum is still behind on bitcoin and will not replace the bitcoin position but ethereum will have its position in the market so people can still invest in ethereum anytime.
