Claiming free bonuses with high wagering requirement from casino to other casinos will be wasting your time and energy only imho. The probability to complete the wagering requirement is so low, so taking it for fun only on your spare time is better instead of forcing yourself to claim it everywhere.
Yea I fell into this trap once, one site gave like a free $30 which I then turned into $100 but then lost it all before I was able to hit the withdraw requirement lol
