Ethereum should have bounced back to the center axle, and the price can go up and down.
Buterin has tweeted both the sharding and PoS are just around the corner. As usually happens after important achievements by developers ETH price will bounce up to conquer new heights. Just sit back and wait.
Long time in anticipation of all this. I hope for an early transition to the POS. And There the price will not keep you waiting, it will go up.
Looks the reverberations of his tweet are being felt in the current price rise. It is not difficult to imagine what would happen if sharding and PoS had come into reality right now.
