That $1,000 barrier is the strongest resistance for any coin, basically. A new coin will always find it at the psychological points of $1, $10 and $100, and these really have nothing to do with technical vision or price ranges. This is purely how the human mind works, because we have 10 fingers, so it seems!
But the good news for ETH is that it broke it so early in the year, and it moved non-stop almost from below $700, so it is showing very good signs of holding at $1k or around there. Next logical barrier is $2k, and then on and on.
Rounded numbers such as $100, $1000 and $10 are the psychologic borders for any coin. Passing these borders is hard, but still possible. Ethereum now is looking like it brake the border down. Let's wait and see, next target will be $1500 for ethereum.
