Do you know that you can make money through your PayPal account? How is that possible? It's possible if you have a PayPal account and a good website.
I haven't actually tried it but some successful bloggers and website owners do try it. They place a PayPal donation button on their site and if the visitors or one of their readers like what is written there, there's a possibility that they will donate a small amount of money in order to see the site going.
It's not a requirement and I do not encourage you to use it but if they give willingly, there's nothing wrong about it. Site owners do not force their readers to give instead they are the ones who must provide useful content to them in the first place.
Anyway, learning to make money online entails time and effort. It also requires us to do some research and read others' works. Apply the 'give and take' principle and I'm sure we're on our way to be successful.
I just want to remind you that it is only an optional. If you think that it's not right to place a PayPal donation button, then don't put it. It all depends on you. I hope you enjoy reading this post.
