Curious as to how everyone uses the MyPoints they collect: redeem every time the achieve and award or let balances built up and only redeem once.

Also, since MyPoints owned by UA and had to declare bankruptcy along with the airline recently, is anyone keeping balances low in case the worst happens and MyPoints shuts down. Of course, I'm hoping that doesn't happen as I really like MyPoints as a way to build my Marriott or HH balances.

Just wondering...
