Any reason for the price drop?
No reason, just buy the dip. You won't regret it. I did, like I said before it's like Christmas when the price drops. Golem is worth more and IMO is not on the same level as Elastic, especially once the devs are done.
+1 Once an innovativative project comes out, smart guys tend to buy cheap for as long time as possible. Like first 4 years of bitcoin history was buying trend and whales didn't let it grow too fast. XEL is young, so its accumulation stage, I hope it will not explode too fast as I'm seeing great longterm potential in it.
