I'm sure it can happen easily (Ethereum price reaches $3000), because I think the next bullrun will happen soon, because next year is the best year for cryptocurrency (ETF announcement and bitcoin halving), so of course now is still the right time to DCA Ethereum until the next bullrun happens, because I am sure that if a bullrun occurs, then the price of Ethereum will increase at least 2x from its ATH price.
3k is definitely coming and anyone investing in ethereum and keeping their coins in cold storage will see good profits during the upcoming years, however even if ethereum did that movement, that will only represent a 50% gain, and while that amount is massive in almost any other market, there are many investors that may think that is an amount that is too low for them.
And because of this it will not surprise me if there were a lot of people out there that decided to pass on investing in ethereum, and instead they took the risk to invest in meme coins and other shitcoins thinking they can get a better performance out of those coins.
