I don't know how to cashout? I am from Romania, what are the possibilities to cashout a large sum of money at once?
You did the most difficult part already, witch is earning crypto.
So Local-BTC would be the way to go.
Localbitcoins is the place lots of people go to buy and sell Bitcoins, and when people ask me where they will sell or buy Bitcoin, I also refer them to LocalBitcoins. But ever since I got into Bitcoin, I have never used LocalBitcoins site for buying and selling, even for once. What I did was find an exchanger through a forum, and he lives in same country with me, yep I know its risky cause you might get scammed, but he has been honest and have been doing business for few years now, and I can tell hes a good guy.
