That's wise yes. To be honest, ETH for me it's completely dead and you know how much I "hyped" it. However, I for one couldn't foresee all this DAO situation and how it just keeps getting worse. So in crypto you really never know. I guess you don't have faith in any altcoin but really, ETH was destined to be around $30 by this time (all based on potential and "hype" we agree).
Right now for me the project is completely dead in the water no matter what they do or it will take many months to recover slowly. What I don't understand is why are we still at $12.
Are you planning to buy back in if it starts dropping to $4-5? What's your bottom? Do you think ETH can recover? I'm sorry to ask so many questions but you seem to have a much more surgically approach (I know you are mostly a trader) and I'm more inclined to long term investment and long positions (within reasonable).
My thoughts are that, besides manipulation, price is being maintained at $12 by ETH holders in denial. They won't admit that it's over or that they made a mistake, so they refuse to sell, and may even buy more. Problem is, they cannot account for new issuance - which isn't being bid outside of their sphere - so price slowly grinds down in BTC terms on low volume. As price sinks, their doubts will grow, and one by one they will pop, which will continue and accelerate the selling into a crescendo.
Provisionally, I would be looking for price to fill the gap at 0.0124 or continue down to psychological support at 0.01 for a possible entry. I would want to see big, high volume sell-offs to validate my moves, I'd then be looking to sell a rebound possibly to 0.015.
Long-term, it's probably best to wait until it's going sideways on lower volatility to decide if you want to get back in or not, rather than trying to guess the bottom. I do think there could be another bubble out in the future though.
Your strategy only works if the Ethereum survives the current crisis, the price will rebound. If not, the price will go lower.
Even if ETH is headed to zero, there will be rebounds based on the behaviour of its holders. I'd say I get it right about 8 times out of 10, which is enough. For the times I get it wrong, I cut my losses. I also think you're looking at different time scales to me - my best trades are the ones completed in a single day - NEM for example, has been fun
