All,
The Jan 15-16th helps improve performance of eth and also sets the stage from POW to POS, the future change to POS is very positive and does the following things;
With PoS there will be less of a need to sell for covering electricity/hardware costs.
Ether earned from staking will probably be added to the stake rather than sold.
As mining is expensive as mentioned above, you cant blame miners for selling the coins they earn which causes price volatility. The reason why a PoS would give you price stability is because it gives the person more incentive to keep the coin than to sell.
Ethereum is also designed to actually be able to LOSE ETH coins after PoS. Meaning instead of the supply constantly appreciating, it could depreciate, hence driving value up even more.
Like Joseph Lublin of eth recently stated the future is bright (he also stated the bottom is in)
