I've seen one before but I lost. A way to earn crypto as easily as solving captchas is also wanted or something that rewards without investment/free. Currently I am mining and farming but being that i dont have a lot its not earning a lot
Its long time that I never tried to do some task on captchas since they are pretty much not profitable since you will jusy waste your time doing it.
But if you insist and still want to do it theb kindly do a research on this
