Im in the same position as you. Some people seem to think there's a 20-30% correction coming after the fork, but even if that's so and you buy before, surely that would be offset by the free coin you get?
I've decided to go in now even though I know the price is high just for the free coin. I'm planning on holding for long term so I dont see a huge problem. IF theres a 20-30% dip at some point, I'm sure it will get back its price and then some. Its been the history so far so hopefully it'll repeat itself.
Any comments/feedback welcome!
