Ethereum looks like it is taking a pretty big dip now might be a good time to buy. or not
I'd leg in. From my reading & lurking in other markets, folks who are surprisingly prescient at calling a top do not have the same prescience when calling a bottom. They come in two flavours:
1. Underlying bulls. These folks think the bottom has been reached long before it has. I actually saw this on a penny stock forum: some fellow unloaded his shares of a gold company at above 60 cents and damn near the peak. But the fellow got back in at 40 cents, and the thing kept sliding to a little above 20 cents.
2. Permabears. These are people who are sometimes strikingly right when calling a top, like the folks who called out the housing-and-mortgage bubble in 2005, 2006 or 2007, but they turn into the proverbial "stopped clock." All of the ones I read were just as bearish (if not moreso) about real estate in 2010 and 2011 when the real-estate market bottomed. And of course, all of them were bearish on the stock market in 2009, 2010, 2011, 2012, 2013...you get the idea.
Given that a prescient call of a top tends to be a one-off, if you're in category #1 [which you sound like] you should hedge by buying ETH in stages. You should also prepare to see your earlier buys go lower before the thing turns around, and tell yourself that you're buying a bargain. Despite the charming counsel of Captain Hindsight, squeezing a buck out of this market is still hard. Fact is, in the last bull run we had it too easy.
