Don't worry, Ethereum will be able to return to the price of 300-400 dollars sooner or later. This is a must. The current price of Ethereum has been seriously underestimated because the market is now suffering from serious oversold.
In my opinion, Eth's reasonable price should be around $500, but it is far below this price now, so we will be profitable now to buy Eth.

Indeed Ethereum is much better than XRP tech and ethereum claim the 2nd position.
Biggest projects based on ethereum blockchain and community supporting and buying at every dip.  
Right now Ethereum is above $150 and I hope in couple of weeks price will cross $200 easily.
What do you think eth can cross $200 line this week or next?  

I hope so but I doubt we have a bullish mode right now what I can see is this is caused by the three hardforks coming in the middle of January especially the constantinople hardforks which is very significant changes from pow to pos, we can really see a bullish mode I think in the next month if no dump after this forks.

Not trying to be a pessimist but i highly doubt we can see such price without any pump from btc, yes eth price is up going regardless of rise in price of btc because of the upcoming eth fork, the big question is what will happen after the fork? Will the price keep moving up or will people who buy at $100 and below will take profit and crash the price?

Am also eger to see the next few days and weeks what it will be for eth and rest of alts as well as btc, but who knows, this is crypto anything is expected, eth has fighting power so hopefully we could easily see such price in near future

can be, cause this is a 33% less reward for the mined block, but the elec cost remain the same, so, there will be a price spike, or lot of miners will choose other coins to mine
here the math is very simple 

Raise your hands if you are excited for the hardfork!! I believe that there is going to be a bull run just as you expected to reach $200 USD. I hope it rises back to $1000 USD. It's been almost 5 years now for Vitalik to finally upgrade Ethereum.

Agreed with you low block reward will put very good impact on the price. I hope so it will help this to find the way to stay on a stable floor. It is on good streak and it will help the people to get satisfied with solid rise.

so what to mine next after Eth go to POS? etc or

Those forks that will generate new coin are probable scam so its useless if you are just buying ETH for those. The real fork is just an upgrade which is the constantinople. And that what will make the network faster and the most awaited change of PoW to PoS is still on the making.
