As Neo has been strong recently and is seen as a good coin, I have gone for a conservative buy-in within the 50-60% range, although if the bulls move on, this could correct lower.
Opinion not advice.

Either way will be interesting to see how the fundamentals really affect the price/market cycles. You can use this as a basecase if you like ;) However, I would be careful not to be too bullish on the tech or market factors... Yes these affect the buy and sell decisions of many, but the market is the market, and right now altcoins are slaves to BTC. If BTC continues to cycle down, it doesnt matter how positive you are about the market, you will loose money if you buy back in too soon.
