I don't know how to cashout? I am from Romania, what are the possibilities to cashout a large sum of money at once?
First upon let me clear you that blockchain is not balance or currency its wallet to store your BTC or eth. With the help of blockchain service you can put your all BTC here its remain safe and secure. Blockchain is not only show you the price charts as well as it keeps your BTC and eth safe. And second one if your friend wants to buy BTC then sell it and take the real cash from it. If you do this with your friend both of you save your transaction fee and you can also sell your BTC at localbitcoins.com.
You shouldnt be telling him that, he already knows that. He just said it in a way that seems more understandable to him. And more over, someone already explained that first. What you should be advising him is not cash out a huge amount at once to avoid his bank blocking his account out of suspicions that hes into a dirty business. You should be withdrawing the money little by little, and taking a out a huge sum at once.
