Hello Bart

Welcome to fonline! Actually, there is no safe place in this game. I believe that you will be very careful next time u will be trading

Are you playing alone? Try to grab one of your real life friends to help you in game. You will see that it is MUCH easier to play with someone else than alone. Do not trust people u dont know in real life. This server is full of trolls, player killers and simply ass holes (there are some nice people too, but chances to meet them are low).
Did u manage to build a tent? What level are u? what is your build and play stile?
When you will be more experienced you will be able to obtain what u lost today in half an hour. Don't give up!
