With some efforts you can earn bitcoin from faucets, forum signature campaigns, glambling (not recomended), trades, etc...
After achieve a good bitcoins amount you could invest It. If you lose all, you don't lose your money.
faucets pay literally nothing. You will make 5 cents per hour if your lucky lol
He also mentioned that some efforts can earn money from gambling and trades as well but without using our money and only with efforts how can one earn money from these methods?
Instead of going with faucets, you can try signature campaign then you will earn some decent amount per week and then you can use that money for trading to earn more. But never use gambling for earning money. If you want some entertainment then only go to gambling.
Yeah you are right! Well at first try gambling but dont be addicted to but you wont be addicted if you keep on loosing thats why you should go for trading! Dont stay in gambling if you dont have luck! Try your knowledge and skills in trading! I promise you can earn a lot from trading if you learn and know how to trade
