Are you talking those bitcoin generator software? If so, nah, you're just dreaming, there's no legit bitcoin generator, I don't even know who's the one who creates such term since bitcoins are only gained from the mining rewards and it needed powerful hardwares such ASIC miners to get some of your shares of the reward.

If you see those websites or from youtube about these generators, obviously its scam. So stay away from them not unless if you want to be scammed.
