I still see the market moving sideways at the moment but I am fairly confident that the recent drop to $160 was the absolute bottom for Ethereum. I decided to add a small amount of ETH every 2 - 3 days when it was under $200 and if you have a break-even price of $700 I would suggest that you also consider adding at regular intervals now whilst it is a favourable price and start to bring your $ cost average down.
Also, if you couple this approach with selling, say, 50% (or even less) of what you bought at the dips, when the price turns in your favor for a while, you will bring the breakeven price down faster, and at the same time not lose an opportunity to have long-term profits (with a small trade-off). But there's a caveat. With crypto, we never know where the true bottom is, and if you think that $160 was the absolute minimum, you may have to rethink your stance if the price crashes past that mark in a free-fall fashion.
