Hello. im usually buying t5. so i know the approximate price of t5 price. but in 2 days. it spike so high. so i kinda curious. what happened ? i saw gw2 spidy. there is a lot of demand in these 2 day.is there a new exploit ? or maybe there is a lot of new player in just 2 days using all the t5[which i doubt]. 
t5 price spike
Could be speculation due to the upcoming Guesting, which will see an influx of new players who will need those mats fairly soon.
Would make more sense if it was low tier spiking though.
I was in frost gore yesterday and noticed that the instaport bots that used to be there 24/7 were gone. Perhaps there has been a recent ban on bots again?

Off topic: I think you might be misunderstanding what guesting is. Guesting is just being able to play on another server temporarily without switching – it has nothing to do with new players at all. It’s not like a trial version or anything.
On topic: my guess, OP, would be that there are simply fewer people going to the level 70-80 areas since they upped loot in lower areas. Therefore, fewer people are in areas with t5 nodes/drops. Therefore, a price spike because there is less supply.
Might also be more demand if people are wanting to max crafting to get achievement points for the new system.
I very honestly doubt it. The price went up a week or so ago to the above 1s prices recently. From gw2spidy, I notice that T5 prices took a large drop on 17-17th December due to large influx of supply. Also, I guess that the snowflake exploit lowered demand for them due to free ectos being created, reducing need for T5 materials. Prices have steadily increased over the past few days and appear to be going stabilizing at the 1s mark.
The price is most unnatural and I will be looking more into it.
