I traded 4 years, with them, and what? They just deleted my account, and for more than 3 weeks I have not seen all my money

I understand that you are frustrated in your situation. However, very often
the people, who complain in forums like this leave out important pieces of information
that are critical for a good interpretation of the situation.
E.g. a user recently complained that Bitstamp shut down his account with a 5-digit
fiat balance and later it became evident that this guy was heavily involved
in dark net activities. At first I was wondering why Bitstamp would shut down a legit
account like this, but later it became obvious that they couldn´t possibly continue
to serve such users unless they want to be accessories for criminal activities.
I´m not implying that you are guilty of the same, but very often Bitstamp´s decisions
to close an account are actually justified.
