The problem is only for who sell eth .. I prefer eth with me 
That exactly what we should do now.price can rebound anytime from any stage,and it only give you a lose if you sell your eth now. I believe this is not the right time for sell as i believe eth price will spike over $300 soon.Based on wishful thinking? This is all uncharted territory. What kind of analysis could possibly make you think with any confidence that a spike straight back up is likely?
I think this drop was very fast and there will probably be a good bounce back up just because of trading, but why "300+ soon"?
The price is actually rebounding nicely but I doubt it will reach 200 any time soon. The 50% haircut -if it does reach 200- will reflect the obvious: All those multi-million ICOS, including current ones in progress, need to dump millions and millions of ETH in the markets and get it in fiat in order to progress and pay for the operations their ICOS promised. Same thing with BTC for most of them admitted both ETH and BTC. In my opinion the crash of this weekend is just the start and it will be followed by many others as this exchange of BTC/ETH for fiat continues inevitably and with new money coming in slowing down, especially after new investors are burned by the crashes.
That, of course, doesn't include the easy manipulation that is quite possible for those with big pockets and the ability to short.
These are very troublesome times with the risk increased significantly. To remain on the fence seems quite appropriate to me.
