so let's say you've got a URL target and the bid is 0.0151 for it (so somebody else is already bidding on it). you bid 0.0152... then four hours later you notice it's gone up to 0.0153. you put in a new bid of 0.0154... then a few hours later you see you've been countered again at 0.0155... and on and on. do you just keep bidding up in those increments 0.0151... 0.0152... 0.0153... 0.0154... ? or is there a better bidding strategy? what do you personally do in that situation?
