I am particularly interested in point 3. Isn't using Paypal with bitcoins a taboo? Has anyone tried the site?
https://steemit.com/bitcoin/@jellytail/3-ways-to-grow-your-bitcoins-or-3-ways-to-lose-your-bitcoins 3. Sell your Bitcoins with a 15% mark-up on xCoins.io
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.
No, I have not tried the site and I would advise against it. Almost all methods to magically "grow" your Bitcoin are either scam or involve significant risk. Besides that selling BTC for fiat trash money is stupid to begin with, accepting Paypal transfers is pure idiocy. The return on investment is likely negative. The site xCoins.io makes profit by outsourcing the risk to the BTC sellers.
If you want more Bitcoin, work for them or sell some stuff. This is far easier and less risky than any investment schemes.
ya.ya.yo!
