Is whoring profitable on a 12k roll??

[spacebetween]

Back when I was playing limit a year ago I would bonuswhore all the time (which means I have an account on most old sites). I've been playing on party/stars for a while. A mix of nl 200 and 400. I'm a losing player at nl 400 but I'm gonna take a shot again when I get to 14-16k, which might be soon depending on how I run. I used to play on party and have rakeback but I don't anymore. For those who still do it, would it be worth it to go for bonus whoring playing medium stakes or its a waste of time? I'm wondering cause even at nl 200 I'm often +-1k everyday so a 100$ bonus is kinda insignificant... its not even a 25ptbb pot.
