$5k is a very easy price that Ethereum will definitely reach in the near future, especially when the next altseason occurs, then the price of Ethereum can definitely reach $ 5k, so now is still the right time to invest in Ethereum, because I'm sure you will definitely get a lot of profit from investing in Ethereum at this time.
Yes. Getting $5k as its new ATH i think is very possible because ethereum at the moment is very bullish. With its current price at $3,273 then its too close for its new predicted ATH.
But let's not forget that price corrections are waiting along the way. The more ethereum goes up, the bigger the chances that price corrections will occur. So i suggest, keep your faith. Just like bitcoin, it may fall but definitely the value will bounce back and recover again.
