Looks like we can enter private keys not generated on 2XPT as well

I'd probably just create a burner wallet that could easily let me view private keys— for convenience's sake— if I wanna play. Or perhaps op could let players drop an address and a signed message from it (sign of ownership) as an alternative login. Maybe it'd feel less threatening for other folks too.
In any case, promising concept op. Good luck!
Its better to be safe than sorry, we arent saying that this site is dangerous but inputting up your privatekey on any website you can found online does impose risks no matter how trustable or credible it would be. The best thing to be done is to make some burner wallet. I do see this not to be that a total dice game but rather it do make out some rolls and win up according into the result. If everything could be that verified without any issues then this concept isnt something new anymore yet we've been through similar idea like this but it is partaking on lottery side and not on a dice based but since the results will be basing up with numbers then it will be just that the same.
AFAIK, it’s not the private of your Bitcoin wallet rather a private generated by the website when you create an account.
The goal of this casino is to operate anonymously that’s why they are using this method as login and destroy the account after 30days which means you can’t use the same key anymore for a longer time. At least this is what I understand on this casino feature.
Alternative log in or having other more options will be always that preferred rather than on having less on which we can actually be able to play without minding much about using up our own keys. Its good to have that self generated wallet created that you can use into.
This is good suggestion but I doubt this will be considered if they want to stick with no data will be saved permanently.
