I have been using PayPal for quite some time. There are other online payment processors but I am not familiar with any of them since I use only PayPal.
My account is set up to transfer my online earnings to my bank. That's all I use it for. I have found it to be reliable and would recommend it.
The only issue I experienced had nothing at all to do with PayPal. A long time ago I got a bogus, phishing email from someone trying to hack my account. They used PayPal's logo and appeared to be them. When I logged on to my actual account I saw nothing wrong so I notified PayPal. They sent me a link and asked me to forward the email to that link, so I did that.
The real PayPal notified me saying that it was indeed a phishing scam and they handled the problem.
Big brother was watching out for me.
