As I've heard bad experience with both, but still need to make money
If you really want to have bitcoin without doing those, you should find a real job and a good campaign here in bitcoin, by having these things you can surely attain the bitcoin you are aiming to have since real money is what you really need in order for you to be able to buy bitcoin. You can not have bitcoin if you are not going to put up a time and effort. You can not cheat on bitcoin that's why you should work hard.
