How did you predict the targets $600 and $5000 ? Elliott wave?
300, 400 and 600-700 are MAJOR support/resistance areas. If this rally takes a typical 5-wave structure the tops should be around those areas (first one already in at $316).
For the next ATH $2k-$5k is just a guess based on gut feeling, no one can claim to have more than that IMO.
