I have said the same thing in my post. I have wagered around 2× of my deposited funds. I wanted to check the rollover requirement terms before making the withdrawal request. Because some casinos have 3× to 5× rollover requirement. I was surprised when I have seen this terms at Betpanda
All deposits must be wagered 10 times (10x) before you can withdraw any deposited funds.
Here is my suggestion, I think what Betpanda need to do is to show the last time when the terms and conditions were last updated. This helps users know if there were recent changes or not. Alternatively, when term changes are made, they could make the users first accept the updated terms before using the platform.
And your suggestion is very valid.
The right approach I've seen with notable companies I deal with, aside from gambling companies, is to either 1. notify me by email of the changes in the Terms and Conditions, and advise me to visit the site ASAP to acknowledge it. or 2. There is an immediate pop-up on my member page on visiting the platform after the new Ts&Cs are updated. This will make sure I am noticed, and I must also sign it electronically before I can do anything on the platform.
By this, no one can ever be left out, and it's the standard.
