Plataforma com valores altos sem segurança

Boa noite..

Acessi um link através do Instagram.. e com bônus ganhei um valor muito alto.. porém para sacar pede para depositar partir de 70reais.. verifiquei e achei erros grotesco de português. Será que é golpe?

Como posso ter certeza?

Hi, can I ask what casino is this ? As for the links on instagram, I wouldn't believe it too much, because there are a lot of such pages on social networks and you have to be careful. 

Regarding the fact that you have to deposit first when making a withdrawal, that's standard procedure, so I wouldn't see a problem with that.

But what I see as as issue is that, as you say, there are errors in the language, which I don't think is trustworthy. 

So I'll wait for an answer as to what casino we are talking about.
