I claim between breaks from watching Netflix and playing dice I can't remember how many times I claim but it's impossible to keep up daily or claim all those 9 BFG daily, I'm not saying it's a waste of time but not worth it if you are in front of the computer just to claim, it's good to claim in between break when you are doing something online.
Nobody can be online 24h a day so claiming 9 BFG daily is impossible and as you say, you shouldn't just stay online just to claim the faucet. But as Toptort mentions, every time you have a break for some reason, it only takes 20s to claim. It is an easy way to gain more BFG tokens.
Get all the BFG tokens that you can get claimed on the faucet and buy on the dip but never play with your BFG token it's very risky I experienced losing half of my BFG token in one of my sessions it's one of my bad experiences, I could lose other coins but losing BFG token has a bad repercussion you can lose a big percentage of your stake rewards.
