I've been asked in several PM's when I'd buy in. Personally, safest bet is anywhere above $2420. I'd hold this all the way up to the bottom of our green channel and re-analyze once we get there.
However, an even safer bet would be to buy LTC instead. LTC will usually follow it's leader BTC. You may not profit as quickly but you have far less to worry about with all of these changes playing out.
