In May of last year I allotted some of my long term capital across three major cryptocurrencies: Bitcoin, Ethereum and Litecoin. This morning I added to my ETH/USD position for the same long term hold.
It has fallen back to levels where there a lot buying pressure took place. I am assuming those bulls that bought at these levels will defend in this area, and look to pick up more should price fall much further. While my first block purchased was under $100 I am happy to add to it at these levels as I think this one in particular has a lot of utility and thus a bright future.
Take a look also at the Google Search Trend on Ethereum. It has gotten quiet recently and that is when I get interested, when few others are. 
Back with more soon.
