Honestly, I really think a lot of people are gonna have different experiences because I believe that the type of document one is verifying with also contributes greatly to how long and easy the verification process would go or last, for example, the experience one applying for a kyc verification with a plain id card will likely be different from one applying for the same with an international passport.
On the note above, i will like to let the op and everyone else know the exchanges am currently verified on and how long it took -
...
Remitano exchange - less than 5 minutes and on first trial.
It might also interest you all to know that i used the same document for verification on all this exchanges, which my drivers license.
First time I've seen someone mention the Remitano exchange. Yes, they're very fast in the verify kyc but they weren't really a full-fledged exchange. More like a local p2p exchange for people to sell/buy their crypto to local currency, VND.
