I prefer gambling and trading, because both are quick ways to make a profit, and I really like these easy-to-understand ways to make money!
Real talk !
I thought campaign would be the most easiest one? Gambling and trading has resemblance, they both posess high level of risks, depends on your capital. Both could give you good returns if your lucky, yet both could lose all your invested capital in a day as well. Whereas, campaigns dont need any funds to invest, yet can make you good money. The only risk involve is not getting paid by the greedy manager.
Well, in campaign you only need to online and do your task to get the payment in token or even in bitcoin. It's not that easy, because you also need to spend your time to do the task but the plus point is you don't need to spend your own money to join a campaign. On the other hand, gambling and trading are needs money to do that both.
