If we consider the zones where a large number of coins have traded as resistance zones (going upward), the by far largest one is in between
250-450. 60%+ of all trade ever has been conducted in this zone.
We have now hit the upper end of the zone. It is too early to say if the breakout will succeed - I actually give it less than 50% chances for today. But same as the infamous 420 level that was tried for 5 times, it finally fell (only in a few days), same will happen with this one, if the trend stays in force.
When 450 falls convincingly, the trade density drops to 1/3, which should mean that it takes approximately 1/3 of the time to advance from 450->550, compared to what it took from 350->450.
At 580 there is the strong resistance of the previous top. After clearing it, there is not much on our way.
The ATH double-top in 0.01-0.011 will in my opinion NOT serve as a STRONG resistance, due to the small amount of coins traded there last times, and the completely different fundamentals now (both adoption and number of coins have multiplied since then).
