Display currency on campaigns page (to prevent others from being fired)
I imported my ads from Google Adwords to test Bing Ads.
I had the currency in Google Adwords in HUF, but accidentally set the currency USD in Bing Ads.
I had a 1000 HUF/day (thats about $3.5/day) budget at Google Adwords, it became $1000/day limit after the Bing Ads import.
As the currency is not displayed on any of the sites I visited (campaign etc.), I was quite pleased that the ads performed really well and did not noticed that I was spending 275x the money I wanted.
All in all, I've spent $840 in a few days, which is about the salary of 2 people for a month here in Hungary, so probably I have to look for another job now.
I talked to the support, they were very kind, and directed me to this forum, so here we are.
