The current price of ETH is $1300, and it will take more than 300% increase to reach $4000, and we don't have much time left so I'm more realistic if I see the potential price of ETH that might be reached is $2000.
That will never come true. It seems like that OP was creating such prediction without even consider the situation in the market. I can even make same prediction for ethereum with higher price than it. Ethereum may able to reach 2k but this may happen once bitcoin will be reaching 30k. I don't even think ethereum can make it alone without the help from bticoin.
