PayPal was previously combined company with eBay as they bought it from it’s main founder long ago, but PayPal is completely separated from eBay so both companies can operate well.
PayPal is great for everyone, like if I own a shopping website then I can integrate PayPal to receive payment from my customer, as well if I want to sell custom eBook I still can do the same.
I use PayPal to receive payment from International website like Freelancer.com and other freelancing websites, as they send payment and I receive them instantly, which is great if you want to get your cash instantly.
You need to signup for an account and then you need to add a verified credit card to become verified and then you need to add your bank account to their website so you can cash-out your money from PayPal it will take less then three days once you cash-out money from your PayPal to receive into your bank account.
So my final word is that yaa PayPal is a great website to send money anywhere at anytime to anyone in world as well receive from them.
Hope my review will help.
