One of the passive income you can get is from the commission from your referrals, that would be a big help if you have a lot of them and if the site or network never fails to operate. Don't forget to help and guide your referrals or else you will lost them because they need to work for you to get the certain percentage of interest.
Yes, I agree! One of my passive income too is via referral commissions, with this way.. i can earn from people i guided and lots of company now was really generous to give referral commission, this is also the easiest way to earn money, but of course make sure that u also gave ur referrals a good company. think also their welfare and not only for your own good.
Thats right mate if you intend to get ref you should also think about those ref that you gather also help them to find their ref to continue the chain the more you have the more passive income that you will able to gain.
