Of course Bitcoin is the cheaper one, you can even send a transaction without any fee with Bitcoin.

yeah that is true. special of paypal is protection to buyer or something like that, if you account get hacked and your money stolen, you can refund it. if you have evidence that your account has been compromised

Who and when did this happen? I've mostly seen the victims losing their money and the scammers earns his money back with chargebacks. I've been using PayPal since 5 years and still I say that it is the least secure payment processor due to their chargeback policy.
Their fee is also very high and hence bitcoins are considered the safest option for users who don't want to get scammed and most don't deal with PayPal unless the buyer is trusted.

Neither. I've never paid a transaction fee on either so you must be occupying some higher transaction fees I suppose.

you can use free cost transaction with paypal. if you choose pay service options in sending money

yeah true. whatever amount bitcoin you send. costs remain the same fee 0.0001, different with paypal more expensive

Every payment processor charges 3-4% currency conversion fee as they are also charged for the same. It may be an online payment processor or a bank in that respect and none convert for free.

I'm actuaoly not all that certain. I think they're both the same. Doesn't matter which one you use.

Paypal's fee is higher than bitcoin, but almost every site on the web support Paypal and bitcoin as payment system, both of type, shopping sites and earning sites. But, obviously bitcoin has better advantages than paypal.
