What does instant mean?

A. it means, instant.

B. 1-2 days.

if it means B., then what language does Binance actually speak? #CustomerFirst

in my case it means B, then my second question is, how is 1-2 days the fastest way to deposit when card payments are actually instant? Funny world we living in. They can state something as instant when it's not, and highlight as fastest when it is not.
