How can you ever be safe, right! Safe means established business, lot of people doing it everyday, earn enough money in the beginning to cover expenses first month. Online means on the web and money means money on a bank account and pay-pal.
Unfortunately, very few sites really offer at-home work that would compare to a normal job. There are a few survey sites that can pay you to do offers and whatnot, but the pay isn’t usually in the hundreds per month. It can help a little with small things though, maybe earn to make grocery money or whatnot.
