156.91 DCR for a ticket

What the hell?
Current ticket price is 158.01 DCR as per Dcrstats.com and I think this will greatly increase in the coming days. It's quite interesting to see that it's only on the 124.37 DCR per ticket last December 4 and now jumped to that number today. What's the reason behind this?

The reason is supply and demand. If you look at the tickets bought on the PoS Ticket Price, DCR chart on dcrstats.com, you will notice ~1500 tickets were bought Dec 6th because the ticket price started going up. This is much more than the average ~700 a day, so the ticket prices spike to average this out. Also with over 51% of all DCR supply staked, there is just less room for tickets.
Yeah, I pretty much understand how the law of supply and demand works. But there were even greater spikes of volume throughout this year which didn't cause such increases in price. That's why I was a little surprised to see such price action. Maybe it's because there's more DCR in the market now, so the same movements happen on a larger scale.
