Edit: I really don't have a strategy here, there are no technical resistance points until 80k (minor one at 60k on the last run up, which might be a good punt if you're looking for a dip).. I am going to sell before 80k and look for a dip at 80k. If the dip is huge I won't buy back, if it's soft then I think it's going further. Lock it in!
The biggest assumption is that we make it that far without a random dump, and I don't trust that they can't happen at any time...
