Welcome bonus - how to wager it to get profit

Hi everyone! I’d like to discuss whether it is possible to get at least some profit when wagering welcome bonuses in online casinos.
I registered in one casino recently. I offered a 200% bonus match for new users and 150 free spins that I could use for slots. It looked like a good offer to me. So I deposited some money, started playing and understood that the wagering requirements do not leave you a chance to make even a little profit. I had too high WR - 45x.
Is there anyone who managed to wager a welcome bonus in a casino and make money with it?
