OK so I've been bonus-stacking semi-seriously for about 18 months now and figured I'd write down the honest verdict before I forget what the answer was.
Setup: 5-6 sites at any given time, $50-100 CAD per welcome offer, only slots, never sticky bonuses. Goal isn't "big win," it's clearing WRs and pocketing whatever real-money remainder survives.
Reality check: it's profitable in the rough sense (positive net over the period) but the hourly rate is bad and the admin is brutal — five logins, five KYC checks, five withdrawal queues, five inboxes full of "come back for a reload" emails. Free spins are life until they're a part-time job.
Worth it for the small-bankroll crowd, definitely. Worth it once you're playing for fun rather than EV-grinding? I'm honestly not sure anymore. Thoughts?
