I wasn't around when litecoin originally went up to $40, but looking at the charts it looks as if its rise this time is a lot more gradual, which I think is good. If it spikes up too hard too soon, I think we already have a nice historical record of what will happen. However if it can rise just $1 or $2 a week with periodic pullbacks, I think it would be a lot easier for people to have confidence it in long term.

So my guess would be it will keep going up, but at a slower pace than before. A nice slow average of $1/week would be another 34 weeks for it to hit $40. I doubt if interest in LTC increases rapidly it would take that long, so a more aggressive prediction of $3 week will put us about 12 weeks out, or sometime in September. I think if it rises any faster it would be unsustainable long term and we could expect a big pullback at some point.
