I am particularly interested in point 3. Isn't using Paypal with bitcoins a taboo? Has anyone tried the site?

xCoins.io is a site that was launched in June with positive reviews. The controversy with this site is that it uses Paypal as its payment processor. xCoins is a middle man that connects buyers and sellers with the former who seeks to buy bitcoins with Credit card or Paypal -- at a 15% markup price. The sellers will receive the proceeds in their Paypal account. Many readers are very likely to disapprove this site because it is using Paypal as the main mechanism for fund transfer since Paypal transactions are reversible by scammers.
I tried selling BTC for PayPal once before but it was to someone that was trusted through localbitcoins and was for almost no profit for me "and a 1-2% lower rate than the market actually", A website offering PayPal for such rate is sketchy to say the least..
