Has some good information even though it's a bit old.
And about dying. You will be doing a lot of it in the beginning. This game has a huge learning curve so don't get down on yourself if you die.

is this a p2win game?, i mean, if i want to be good at this game, i have to buy gold?

Eh it kind of turned into that. But you still can do fine without paying.

I'm so afraid to lose my stuff ;_;!

And boom, i lost everything HAHAHA

Rip. :/
You can save items you want in a free vault that comes with all chars. If you want to store more items you can make new accounts, and open up a new tab in browser or whatever to transfer items.
