I share the experience I had at Betzela.com:

When registering and asked me for a password with at least one capital, one digit and that it be in English!

It is the first time that it happens to me that it suggests the language of the password! That is, I cannot put ppr example "Abchy26" does not allow me to register! I tried "Adventure1" and it perfectly accepted me.

It made me hesitate and I stepped back. I did not finish the registration.

Why identify the language of my password? I don't know, it made me hesitate to deposit with a credit card, for example.

Or this has some logic that I do not know.

I do not see the sense.

I am not saying that other casinos cannot see or dispose of all our data, it is certainly our trust that we place in them. But being so open about conditioning the language of the password scared me.

Les comparto la experiencia que tuve en Betzela.com:

Al registrarme y me pedía una contrase?a con al menos una mayuscula, un dígito y que sea en ingles!

Es la primera vez que me pasa que me sugiere el idioma de la contrase?a! Es decir, no puedo colocar ppr ejemplo "Abchy26" no me permite registrarme! Probé con "Adventure1" y perfectamente me aceptaba.

Me hizo dudar y di un paso atrás. No finalicé el registro.

Porque identifica el idioma de mi contrase?a? No lo se, me hizo dudar en depositar eventualmente con tarjeta de crédito por ejemplo.

O esto tiene alguna lógica que yo desconozca.

No le veo el sentido.

No estoy diciendo que los demas casinos no puedan ver o disponer de todos nuestros datos, es ciertamente nuestra confianza la que depositamos en ellos. Pero ser así tan abiertos en condicionar el idioma de la contrase?a me asustó.

If u read carefully , it 

says:Password should contain upper and lower-case English letters, ///

By english letter they probably mean English alphabet cuz maybe someone try to put in the German language: ?, ?, ü and ?, or in Norway /Danish ? ,?,? .. or some other symbols.. 

The reason for this is probably their database and UTF char set, or their hash... 

So it's not english word,it's just alphabet letters :) 

I think Inferno is right. They mean the English alphabet so no Chinese letters or special symbols as well.

Something similar has happened to me. But with the last name, because mine has the letter ?.

Then it won't let me advance in the registry because it tells me: it has characters that are not supported.

However in this case, the password was a combination of letters and number in Spanish, and I was not allowed to register.

Ya me ha pasado algo similar. Pero con el apellido, porque el mío tiene la letra ?.

Entonces no me deja avanzar en el registro porque me dice: posee caracteres que no son admitidos.

Sin embargo en este caso, la contrase?a era una combinación de letras y número en espa?ol, y no me permitió el registro. 

Well, I have also had a similar bad experience and that seems stupid ... They have to consider all languages and their characteristics.

Pues, también he tenido una mala experiencia similar y eso me parece estúpido...Tienen que considerar a todas idiomas y sus caracteristicas.
