those of you that are familiar with cc scores for churning in canada, tell me whats the impact of having like 10 newly added accounts (mostly cc's) added at once, worst case scenario to my understanding is it reduces avg age but even then how "bad" is it to have so many new accounts for say in consideration of future cc applications.
lastly im not worried about overstretching my credit, so how long should I keep these cc's before cancelling them, im thinking like 6 months because id like to do new apps after that period
