So I was trying a campaign for a country and because of my high ctr I was paying like 0.11 cent a click but my bid was 0.70...
once I saw that cpc is 0.11 I reduced my bid to 0.15 thinking that it would make it would reduce my cpc more, but its already close to an hour and suddenly traffic has stopped coming. No clicks at all neither into facebook nor on my prosper after that bid reduction.
Any idea whats going on?
I've experienced the same issue when trying to adjust the bid and achieve a lower cpc.
From what I understand and can relate to experience is that it is always wise to leave your bid at the price that you initially set and allow your ctr and account history to dictate the cpc.
I'd be interested to know if anyone has had any success with adjusting the bid to achieve lower cpc's though.
Happend today for us as well however traffic started to roll in after awhile.
Going from $0.70 down to $0.15 is a pretty big jump. I realize that $0.15 was still more than you were actually paying but their system probably saw that as a huge reduction in your bid.
What I've seen most people recommend is to reduce by $0.02 every couple hours until you hit that point where traffic slows down. Then you know how low you can go.
Personally, I don't mess with my bids too much. If I have a good CTR then the CPC will come down on its own.

Are your budgets and daily spend limits adequate? Maybe it's attempting to spread your spend over the day.
Did you send enough impressions to let it concretely establish the creative's CTR before dropping the bids?
A friend of mine never lowers his bid. He bids way over the maximum suggested bid and just keeps it at that. For him, when the CTR goes up, the system charges him the minimum suggested bid no matter how high his bid is. So for example, suggested bid is 0.10 - 0.24 and he bids 0.50, he still gets charged 0.10 per click.
